From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- .../classpath/gnu/xml/aelfred2/JAXPFactory.java | 230 + libjava/classpath/gnu/xml/aelfred2/SAXDriver.java | 1609

This package contains Ælfred2, which includes an +enhanced SAX2-compatible version of the Ælfred +non-validating XML parser, a modular (and hence optional) +DTD validating parser, and modular (and hence optional) +JAXP glue to those. +Use these like any other SAX2 parsers.

About Ælfred

+ +

Ælfred is a XML parser written in the java programming language. + +

Design Principles

+ +

In most Java applets and applications, XML should not be the central +feature; instead, XML is the means to another end, such as loading +configuration information, reading meta-data, or parsing transactions.

+ +

When an XML parser is only a single component of a much larger +program, it cannot be large, slow, or resource-intensive. With Java +applets, in particular, code size is a significant issue. The standard +modem is still not operating at 56 Kbaud, or sometimes even with data +compression. Assuming an uncompressed 28.8 Kbaud modem, only about +3 KBytes can be downloaded in one second; compression often doubles +that speed, but a V.90 modem may not provide another doubling. When +used with embedded processors, similar size concerns apply.

+ +

Ælfred is designed for easy and efficient use over the Internet, +based on the following principles:

    + +
  1. Ælfred must be as small as possible, so that it doesn't add too + much to an applet's download time.
    2. + +
  2. Ælfred must use as few class files as possible, to minimize the + number of HTTP connections necessary. (The use of JAR files has made this + be less of a concern.)
    3. + +
  3. Ælfred must be compatible with most or all Java implementations + and platforms. (Write once, run anywhere.)
    4. + +
  4. Ælfred must use as little memory as possible, so that it does + not take away resources from the rest of your program. (It doesn't force + you to use DOM or a similar costly data structure API.)
    5. + +
  5. Ælfred must run as fast as possible, so that it does not slow down + the rest of your program.
    6. + +
  6. Ælfred must produce correct output for well-formed and valid + documents, but need not reject every document that is not valid or + not well-formed. (In Ælfred2, correctness was a bigger concern + than in the original version; and a validation option is available.)
    7. + +
  7. Ælfred must provide full internationalization from the first + release. (Ælfred2 now automatically handles all encodings + supported by the underlying JVM; previous versions handled only + UTF-8, UTF_16, ASCII, and ISO-8859-1.)
    8. + +
+ +

As you can see from this list, Ælfred is designed for production +use, but neither validation nor perfect conformance was a requirement. +Good validating parsers exist, including one in this package, +and you should use them as appropriate. (See conformance reviews +available at http://www.xml.com) +

+ +

One of the main goals of Ælfred2 was to significantly improve +conformance, while not significantly affecting the other goals stated above. +Since the only use of this parser is with SAX, some classes could be +removed, and so the overall size of Ælfred was actually reduced. +Subsequent performance work produced a notable speedup (over twenty +percent on larger files). That is, the tradeoffs between speed, size, and +conformance were re-targeted towards conformance and support of newer APIs +(SAX2), with a a positive performance impact.

+ +

The role anticipated for this version of Ælfred is as a +lightweight Free Software SAX parser that can be used in essentially every +Java program where the handful of conformance violations (noted below) +are acceptable. +That certainly includes applets, and +nowadays one must also mention embedded systems as being even more +size-critical. +At this writing, all parsers that are more conformant are +significantly larger, even when counting the optional +validation support in this version of Ælfred.

+ + +

About the Name Ælfred

+ +

Ælfred the Great (AElfred in ASCII) was King of Wessex, and +some say of King of England, at the time of his death in 899 AD. +Ælfred introduced a wide-spread literacy program in the hope that +his people would learn to read English, at least, if Latin was too +difficult for them. This Ælfred hopes to bring another sort of +literacy to Java, using XML, at least, if full SGML is too difficult.

+ +

The initial Æ ligature ("AE)" is also a reminder that XML is +not limited to ASCII.

+ + +

Character Encodings

+ +

The Ælfred parser currently builds in support for a handful +of input encodings. Of course these include UTF-8 and UTF-16, which +all XML parsers are required to support:

+ +

If you use any encoding other than UTF-8 or UTF-16 you should +make sure to label your data appropriately:

+ +
+<?xml version="1.0" encoding="ISO-8859-15"?> +
+ +

Encodings accessed through java.io.InputStreamReader +are now fully supported for both external labels (such as MIME types) +and internal types (as shown above). +There is one limitation in the support for internal labels: +the encodings must be derived from the US-ASCII encoding, +the EBCDIC family of encodings is not recognized. +Note that Java defines its +own encoding names, which don't always correspond to the standard +Internet encoding names defined by the IETF/IANA, and that Java +may even require use of nonstandard encoding names. +Please report +such problems; some of them can be worked around in this parser, +and many can be worked around by using external labels. +

+ +

Note that if you are using the Euro symbol with an fixed length +eight bit encoding, you should probably be using the encoding label +iso-8859-15 or, with a Microsoft OS, cp-1252. +Of course, UTF-8 and UTF-16 handle the Euro symbol directly. +

+ + +

Known Conformance Violations

+ +

Known conformance issues should be of negligible importance for +most applications, and include:

+ +

When tested against the July 12, 1999 version of the OASIS +XML Conformance test suite, an earlier version passed 1057 of 1067 tests. +That contrasts with the original version, which passed 867. The +current parser is top-ranked in terms of conformance, as is its +validating sibling (which has some additional conformance violations +imposed on it by SAX2 API deficiencies as well as some of the more +curious SGML layering artifacts found in the XML specification).

+ +

The XML 1.0 specification itself was not without problems, +and after some delays the W3C has come out with a revised +"second edition" specification. While that doesn't resolve all +the problems identified the XML specification, many of the most +egregious problems have been resolved. (You still need to drink +magic Kool-Aid before some DTD-related issues make sense.) +To the extent possible, this parser conforms to that second +edition specification, and does well against corrected versions +of the OASIS/NIST XML conformance test cases. See http://xmlconf.sourceforge.net +for more information about SAX2/XML conformance testing.

Some of this documentation was modified from the original +Ælfred README.txt file. All of it has been updated.

+ +

+ + +

Changes Since the last Microstar Release

+ +

As noted above, Microstar has not updated this parser since +the summer of 1998, when it released version 1.2a on its web site. +This release is intended to benefit the developer community by +refocusing the API on SAX2, and improving conformance to the extent +that most developers should not need to use another XML parser.

+ +

The code has been cleaned up (referring to the XML 1.0 spec in +all the production numbers in +comments, rather than some preliminary draft, for one example) and +has been sped up a bit as well. +JAXP support has been added, although developers are still +strongly encouraged to use the SAX2 APIs directly.

+ + +

SAX2 Support

+ +

The original version of Ælfred did not support the +SAX2 APIs.

+ +

This version supports the SAX2 APIs, exposing the standard +boolean feature descriptors. It supports the "DeclHandler" property +to provide access to all DTD declarations not already exposed +through the SAX1 API. The "LexicalHandler" property is supported, +exposing entity boundaries (including the unnamed external subset) and +things like comments and CDATA boundaries. SAX1 compatibility is +currently provided.

+ + +

Validation

+ +

In the 'pipeline' package in this same software distribution is an +XML Validation component +using any full SAX2 event stream (including all document type declarations) +to validate. There is now a XmlReader class +which combines that class and this enhanced Ælfred parser, creating +an optionally validating SAX2 parser.

+ +

As noted in the documentation for that validating component, certain +validity constraints can't reliably be tested by a layered validator. +These include all constraints relying on +layering violations (exposing XML at the level of tokens or below, +required since XML isn't a context-free grammar), some that +SAX2 doesn't support, and a few others. The resulting validating +parser is conformant enough for most applications that aren't doing +strange SGML tricks with DTDs. +Moreover, that validating filter can be used without +a parser ... any application component that emits SAX event streams +can DTD-validate its output on demand.

+ +

You want Smaller?

+ +

You'll have noticed that the original version of Ælfred +had small size as a top goal. Ælfred2 normally includes a +DTD validation layer, but you can package without that. +Similarly, JAXP factory support is available but optional. +Then the main added cost due to this revision are for +supporting the SAX2 API itself; DTD validation is as +cleanly layered as allowed by SAX2.

+ +

Bugs Fixed

+ +

Bugs fixed in Ælfred2 include:

+ +
    +
  1. Originally Ælfred didn't close file descriptors, which + led to file descriptor leakage on programs which ran for any + length of time.
    2. + +
  2. NOTATION declarations without system identifiers are + now handled correctly.
    3. + +
  3. DTD events are now reported for all invocations of a + given parser, not just the first one.
    4. + +
  4. More correct character handling:
      + +
    • Rejects out-of-range characters, both in text and in + character references.
      • + +
    • Correctly handles character references that expand to + surrogate pairs.
      • + +
    • Correctly handles UTF-8 encodings of surrogate pairs.
      • + +
    • Correctly handles Unicode 3.1 rules about illegal UTF-8 + encodings: there is only one legal encoding per character.
      • + +
    • PUBLIC identifiers are now rejected if they have illegal + characters.
      • + +
    • The parser is more correct about what characters are allowed + in names and name tokens. Uses Unicode rules (built in to Java) + rather than the voluminous XML rules, although some extensions + have been made to match XML rules more closely.
      • + +
    • Line ends are now normalized to newlines in all known + cases.
      • + +
    5. + +
  5. Certain validity errors were previously treated as well + formedness violations.
      + +
    • Repeated declarations of an element type are no + longer fatal errors.
      • + +
    • Undeclared parameter entity references are no longer + fatal errors.
      • + +
    6. + +
  6. Attribute handling is improved:
      + +
    • Whitespace must exist between attributes.
      • + +
    • Only one value for a given attribute is permitted.
      • + +
    • ATTLIST declarations don't need to declare attributes.
      • + +
    • Attribute values are normalized when required.
      • + +
    • Tabs in attribute values are normalized to spaces.
      • + +
    • Attribute values containing a literal "<" are rejected.
      • + +
    7. + +
  7. More correct entity handling:
      + +
    • Whitespace must precede NDATA when declaring unparsed + entities.
      • + +
    • Parameter entity declarations may not have NDATA annotations.
      • + +
    • The XML specification has a bug in that it doesn't specify + that certain contexts exist within which parameter entity + expansion must not be performed. Lacking an offical erratum, + this parser now disables such expansion inside comments, + processing instructions, ignored sections, public identifiers, + and parts of entity declarations.
      • + +
    • Entity expansions that include quote characters no longer + confuse parsing of strings using such expansions.
      • + +
    • Whitespace in the values of internal entities is not mapped + to space characters.
      • + +
    • General Entity references in attribute defaults within the + DTD now cause fatal errors when the entity is not defined at the + time it is referenced.
      • + +
    • Malformed general entity references in entity declarations are + now detected.
      • + +
    8. + +
  8. Neither conditional sections + nor parameter entity references within markup declarations + are permitted in the internal subset.
    9. + +
  9. Processing instructions whose target names are "XML" + (ignoring case) are now rejected.
    10. + +
  10. Comments may not include "--".
    11. + +
  11. Most "]]>" sequences in text are rejected.
    12. + +
  12. Correct syntax for standalone declarations is enforced.
    13. + +
  13. Setting a locale for diagnostics only produces an exception + if the language of that locale isn't English.
    14. + +
  14. Some more encoding names are recognized. These include the + Unicode 3.0 variants of UTF-16 (UTF-16BE, UTF-16LE) as well as + US-ASCII and a few commonly seen synonyms.
    15. + +
  15. Text (from character content, PIs, or comments) large enough + not to fit into internal buffers is now handled correctly even in + some cases which were originally handled incorrectly.
    16. + +
  16. Content is now reported for element types for which attributes + have been declared, but no content model is known. (Such documents + are invalid, but may still be well formed.)
    17. + +
+ +

Other bugs may also have been fixed.

+ +

For better overall validation support, some of the validity +constraints that can't be verified using the SAX2 event stream +are now reported directly by Ælfred2.

"Attr" implementation. In DOM, attributes cost quite a lot of + * memory because their values are complex structures rather than just + * simple strings. To reduce your costs, avoid having more than one + * child of an attribute; stick to a single Text node child, and ignore + * even that by using the attribute's "nodeValue" property.

+ * + *

As a bit of general advice, only look at attribute modification + * events through the DOMAttrModified event (sent to the associated + * element). Implementations are not guaranteed to report other events + * in the same order, so you're very likely to write nonportable code if + * you monitor events at the "children of Attr" level.

+ * + *

At this writing, not all attribute modifications will cause the + * DOMAttrModified event to be triggered ... only the ones using the string + * methods (setNodeValue, setValue, and Element.setAttribute) to modify + * those values. That is, if you manipulate those children directly, + * elements won't get notified that attribute values have changed. + * The natural fix for that will report other modifications, but won't + * be able to expose "previous" attribute value; it'll need to be cached + * or something (at which point why bother using child nodes).

+ * + *

You are strongly advised not to use "children" of any attribute + * nodes you work with.

"EntityReference" implementation (reference to parsed entity). + * This is a non-core DOM class, supporting the "XML" feature. + * It does not represent builtin entities (such as "&amp;") + * or character references, which are always directly expanded in + * DOM trees.

+ * + *

+This is a Free Software DOM Level 3 implementation, supporting these features: +

+It is intended to be a reasonable base both for +experimentation and supporting additional DOM modules as clean layers. +

+ +

+Note that while DOM does not specify its behavior in the +face of concurrent access, this implementation does. +Specifically: +

+

+ +

Design Goals

+ +

+A number of DOM implementations are available in Java, including +commercial ones from Sun, IBM, Oracle, and DataChannel as well as +noncommercial ones from Docuverse, OpenXML, and Silfide. Why have +another? Some of the goals of this version: +

+ + + +

+This also works with the GNU Compiler for Java (GCJ). GCJ promises +to be quite the environment for programming Java, both directly and from +C++ using the new CNI interfaces (which really use C++, unlike JNI).

+ + +

Open Issues

+ +

At this writing:

+ + +

+I ran a profiler a few times and remove some of the performance hotspots, +but it's not tuned. Reporting mutation events, in particular, is +rather costly -- it started at about a 40% penalty for appendNode calls, +I've got it down around 12%, but it'll be hard to shrink it much further. +The overall code size is relatively small, though you may want to be rid of +many of the unused DOM interface classes (HTML, CSS, and so on). +

+ + +

Features of this Package

+ +

Starting with DOM Level 2, you can really see that DOM is constructed +as a bunch of optional modules around a core of either XML or HTML +functionality. Different implementations will support different optional +modules. This implementation provides a set of features that should be +useful if you're not depending on the HTML functionality (lots of convenience +functions that mostly don't buy much except API surface area) and user +interface support. That is, browsers will want more -- but what they +need should be cleanly layered over what's already here.

+ +

Core Feature Set: "XML"

+ +

This DOM implementation supports the "XML" feature set, which basically +gets you four things over the bare core (which you're officially not supposed +to implement except in conjunction with the "XML" or "HTML" feature). In +order of decreasing utility, those four things are:

    + +
  1. ProcessingInstruction nodes. These are probably the most + valuable thing. Handy little buggers, in part because all the APIs + you need to use them are provided, and they're designed to let you + escape XML document structure rules in controlled ways.
    2. + +
  2. CDATASection nodes. These are of of limited utility since CDATA + is just text that prints funny. These are of use to some sorts of + applications, though I encourage folk to not use them.
    3. + +
  3. DocumentType nodes, and associated Notation and Entity nodes. + These appear to be useless. Briefly, these "Type" nodes expose no + typing information. They're only really usable to expose some lexical + structure that almost every application needs to ignore. (XML editors + might like to see them, but they need true typing information much more.) + I strongly encourage people not to use these.
    4. + +
  4. EntityReference nodes can show up. These are actively annoying, + since they add an extra level of hierarchy, are the cause of most of + the complexity in attribute values, and their contents are immutable. + Avoid these.
    5. + +
+ +

Optional Feature Sets: "Events", and friends

+ +

Events may be one of the more interesting new features in Level 2. +This package provides the core feature set and exposes mutation events. +No gooey events though; if you want that, write a layered implementation!

+ +

Three mutation events aren't currently generated:

+ +

In addition, certain kinds of attribute modification aren't reported. +A fix is known, but it couldn't report the previous value of the attribute. +More work could fix all of this (as well as reduce the generally high cost +of childful attributes), but that's not been done yet.

+ +

Also, note that it is a Bad Thing™ to have the listener +for a mutation event change the ancestry for the target of that event. +Or to prevent mutation events from bubbling to where they're needed. +Just don't do those, OK?

+ +

As an experimental feature (named "USER-Events"), you can provide +your own "user" events. Just name them anything starting with "USER-" +and you're set. Dispatch them through, bubbling, capturing, or what +ever takes your fancy. One important thing you can't currently do is +pass any data (like an object) with those events. Maybe later there +will be a "UserEvent" interface letting you get some substantial use +out of this mechanism even if you're not "inside" of a DOM package.

+ +

You can create and send HTML events. Ditto UIEvents. Since DOM +doesn't require a UI, it's the UI's job to send them; perhaps that's +part of your application.

+ +

This package may be built without the ability to report mutation +events, gaining a significant speedup in DOM construction time. However, +if that is done then certain other features -- notably node iterators +and getElementsByTagname -- will not be available. + + +

Optional Feature: "Traversal"

+ +

Each DOM node has all you need to walk to everything connected +to that node. Lightweight, efficient utilities are easily layered on +top of just the core APIs.

+ +

Traversal APIs are an optional part of DOM Level 2, providing +a not-so-lightweight way to walk over DOM trees, if your application +didn't already have such utilities for use with data represented via +DOM. Implementing this helped debug the (optional) event and mutation +event subsystems, so it's provided here.

+ +

At this writing, the "TreeWalker" interface isn't implemented.

+ + + +

DOM Functionality to Avoid

+ +

For what appear to be a combination of historical and "committee +logic" reasons, DOM has a number of features which I strongly advise +you to avoid using in your library and application code. These +include the following types of DOM nodes; see the documentation for the +implementation class for more information:

+ +

If you really need to use unparsed entities or notations, use SAX; +it offers better support for all DTD-related functionality. +It also exposes actual +document typing information (such as element content models).

+ +

Also, when accessing attribute values, use methods that provide their +values as single strings, rather than those which expose value substructure +(Text and EntityReference nodes). (See the DomAttr +documentation for more information.)

+ +

Note that many of these features were provided as partial support for +editor functionality (including the incomplete DTD access). Full editor +functionality requires access to potentially malformed lexical structure, +at the level of unparsed tokens and below. Access at such levels is so +complex that using it in non-editor applications sacrifices all the +benefits of XML; editor aplications need extremely specialized APIs.

+ +

(This isn't a slam against DTDs, note; only against the broken support +for them in DOM. Even despite inclusion of some dubious SGML legacy features +such as notations and unparsed entities, +and the ongoing proliferation of alternative schema and validation tools, +DTDs are still the most widely adopted tool +to constrain XML document structure. +Alternative schemes generally focus on data transfer style +applications; open document architectures comparable to +DocBook 4.0 don't yet exist in the schema world. +Feel free to use DTDs; just don't expect DOM to help you.)

    In effect, this makes a remote procedure call to the URI, with the + * request and response document syntax as chosen by the application. + * Note that all the input events must be seen, and sent to the URI, + * before the first output event can be seen.

    You are advised to avoid restricting yourself to an "RPC" model + * for distributed computation. With a World Wide Web, network latencies + * and failures (e.g. non-availability) + * are significant; adopting a "procedure" model, rather than a workflow + * model where bulk requests are sent and worked on asynchronously, is not + * generally an optimal system-wide architecture. When the messages may + * need authentication, such as with an OpenPGP signature, or when server + * loads don't argue in favor of immediate responses, non-RPC models can + * be advantageous. (So-called "peer to peer" computing models are one + * additional type of model, though too often that term is applied to + * systems that still have a centralized control structure.) + * + *

It can be constructed + * in two ways:

    + * + *

    Additionally, SAX handlers may be assigned, which completely replace + * the "upstream" view (through {@link EventConsumer}) of handlers, initially + * null or the "next" consumer provided to the constructor. To make + * it easier to build specialized filter classes, this class implements + * all the standard SAX consumer handlers, and those implementations + * delegate "downstream" to the consumer accessed by {@link #getNext}. + * + *

    The simplest way to create a custom a filter class is to create a + * subclass which overrides one or more handler interface methods. The + * constructor for that subclass then registers itself as a handler for + * those interfaces using a call such as setContentHandler(this), + * so the "upstream" view of event delivery is modified from the state + * established in the base class constructor. That way, + * the overridden methods intercept those event callbacks + * as they go "downstream", and + * all other event callbacks will pass events to any next consumer. + * Overridden methods may invoke superclass methods (perhaps after modifying + * parameters) if they wish to delegate such calls. Such subclasses + * should use {@link #getErrorHandler} to report errors using the + * common error reporting mechanism. + * + *

    Another important technique is to construct a filter consisting + * of only a few specific types of handler. For example, one could easily + * prune out lexical events or various declarations by providing handlers + * which don't pass those events downstream, or by providing null handlers. + * + *

    + * + *

    This may be viewed as the consumer oriented analogue of the SAX2 + * {@link org.xml.sax.helpers.XMLFilterImpl XMLFilterImpl} class. + * Key differences include:

    + * + *

    The {@link #chainTo chainTo()} convenience routine supports chaining to + * an XMLFilterImpl, in its role as a limited functionality event + * consumer. Its event producer role ({@link XMLFilter}) is ignored. + * + *

    + * + *

    The {@link #bind bind()} routine may be used associate event pipelines + * with any kind of {@link XMLReader} that will produce the events. + * Such pipelines don't necessarily need to have any members which are + * implemented using this class.

    StageParameterTerminusDescription
    domnone yes Applications code can access a DOM Document built + from the input event stream. When used as a filter, this buffers + data up to an endDocument call, and then uses a DOM parser + to report everything that has been recorded (which can easily be + less than what was reported to it).
    nsfixnonenoThis stage ensures that the XML element and attribute + names in its output use namespace prefixes and declarations correctly. + That is, so that they match the "Namespace plus LocalName" naming data + with which each XML element and attribute is already associated.
    nullnoneyesThis stage ignores all input event data.
    serverrequired
    server URL     		noSends its input as XML request to a remote server, + normally a web application server using the HTTP or HTTPS protocols. + The output of this stage is the parsed response from that server.
    teerequired
    first pipeline    		noThis sends its events down two paths; its parameter + is a pipeline descriptor for the first path, and the second path + is the output of this stage.
    validatenoneyesThis checks for validity errors, and reports them + through its error handler. The input must include declaration events + and some lexical events.
    wfnoneyes This class provides some basic "well formedness" + tests on the input event stream, and reports a fatal error if any + of them fail. One example: start/end calls for elements must match. + No SAX parser is permitted to produce malformed output, but other + components can easily do so.
    writerequired
    "stdout", "stderr", or filename    		yes Writes its input to the specified output, as pretty + printed XML text encoded using UTF-8. Input events must be well + formed and "namespace fixed", else the output won't be XML (or possibly + namespace) conformant. The symbolic names represent + System.out and System.err respectively; names must + correspond to files which don't yet exist.
    xhtmlrequired
    "stdout", "stderr", or filename    		yes Like write (above), except that XHTML rules + are followed. The XHTML 1.0 Transitional document type is declared, + and only ASCII characters are written (for interoperability). Other + characters are written as entity or character references; the text is + pretty printed.
    xincludenonenoThis stage handles XInclude processing. + This is like entity inclusion, except that the included content + is declared in-line rather than in the DTD at the beginning of + a document. +
    xsltrequired
    XSLT stylesheet URI    		noThis stage handles XSLT transformation + according to a stylesheet. + The implementation of the transformation may not actually + stream data, although if such an XSLT engine is in use + then that can happen. +
    + + *

    Note that {@link EventFilter#bind} can automatically eliminate + * some filters by setting SAX2 parser features appropriately. This means + * that you can routinely put filters like "nsfix", "validate", or "wf" at the + * front of a pipeline (for components that need inputs conditioned to match + * that level of correctness), and know that it won't actually be used unless + * it's absolutely necessary. + * + * @author David Brownell + */ +public class PipelineFactory +{ + /** + * Creates a simple pipeline according to the description string passed in. + */ + public static EventConsumer createPipeline (String description) + throws IOException + { + return createPipeline (description, null); + } + + /** + * Extends an existing pipeline by prepending the filter pipeline to the + * specified consumer.

It relies on the + * producer of SAX events to:

      + * + *
    1. Conform to the specification of a non-validating XML parser that + * reads all external entities, reported using SAX2 events.
      2. + * + *
    2. Report ignorable whitespace as such (through the ContentHandler + * interface). This is, strictly speaking, optional for nonvalidating + * XML processors.
      3. + * + *
    3. Make SAX2 DeclHandler callbacks, with default + * attribute values already normalized (and without "<").
      4. + * + *
    4. Make SAX2 LexicalHandler startDTD() and endDTD () + * callbacks.
      5. + * + *
    5. Act as if the (URI)/namespace-prefixes property were + * set to true, by providing XML 1.0 names and all xmlns* + * attributes (rather than omitting either or both).
      6. + * + *
    + * + *

    At this writing, the major SAX2 parsers (such as Ælfred2, + * Crimson, and Xerces) meet these requirements, and this validation + * module is used by the optional Ælfred2 validation support. + *

    + * + *

    Note that because this is a layered validator, it has to duplicate some + * work that the parser is doing; there are also other cost to layering. + * However, because of layering it doesn't need a parser in order + * to work! You can use it with anything that generates SAX events, such + * as an application component that wants to detect invalid content in + * a changed area without validating an entire document, or which wants to + * ensure that it doesn't write invalid data to a communications partner.

    + * + *

    Also, note that because this is a layered validator, the line numbers + * reported for some errors may seem strange. For example, if an element does + * not permit character content, the validator + * will use the locator provided to it. + * That might reflect the last character of a characters event + * callback, rather than the first non-whitespace character.

    + * + *
    + * + * + * + *

    Current limitations of the validation performed are in roughly three + * categories.

    + * + *

    The first category represents constraints which demand violations + * of software layering: exposing lexical details, one of the first things + * that application programming interfaces (APIs) hide. These + * invariably relate to XML entity handling, and to historical oddities + * of the XML validation semantics. Curiously, + * recent (Autumn 1999) conformance testing showed that these constraints are + * among those handled worst by existing XML validating parsers. Arguments + * have been made that each of these VCs should be turned into WFCs (most + * of them) or discarded (popular for the standalone declaration); in short, + * that these are bugs in the XML specification (not all via SGML):

    + * + *

    The second category of limitations on this validation represent + * constraints associated with information that is not guaranteed to be + * available (or in one case, is guaranteed not to be available, + * through the SAX2 API:

    + * + *

    A third category relates to ease of implementation. (Think of this + * as "bugs".) The most notable issue here is character handling. Rather + * than attempting to implement the voluminous character tables in the XML + * specification (Appendix B), Unicode rules are used directly from + * the java.lang.Character class. Recent JVMs have begun to diverge from + * the original specification for that class (Unicode 2.0), meaning that + * different JVMs may handle that aspect of conformance differently. + *

    This package exposes a kind of XML processing pipeline, based on sending +SAX events, which can be used as components of application architectures. +Pipelines are used to convey streams of processing events from a producer +to one or more consumers, and to let each consumer control the data seen by +later consumers. + +

    There is a PipelineFactory class which +accepts a syntax describing how to construct some simple pipelines. Strings +describing such pipelines can be used in command line tools (see the +DoParse class) +and in other places that it is +useful to let processing be easily reconfigured. Pipelines can of course +be constructed programmatically, providing access to options that the +factory won't. + +

    Web applications are supported by making it easy for servlets (or +non-Java web application components) to be part of a pipeline. They can +originate XML (or XHTML) data through an InputSource or in +response to XML messages sent from clients using CallFilter +pipeline stages. Such facilities are available using the simple syntax +for pipeline construction. + + +

    Programming Models

    + +

    Pipelines should be simple to understand. + +

    + + +

    Producers: XMLReader or Custom

    + +

    Many producers will be SAX2 XMLReader objects, and +will read (pull) data which is then written (pushed) as events. +Typically these will parse XML text (acquired from +org.xml.sax.helpers.XMLReaderFactory) or a DOM tree +(using a DomParser) +These may be bound to event consumer using a convenience routine, +EventFilter.bind(). +Once bound, these producers may be given additional documents to +sent through its pipeline. + +

    In other cases, you will write producers yourself. For example, some +data structures might know how to write themselves out using one or +more XML models, expressed as sequences of SAX2 event callbacks. +An application module might +itself be a producer, issuing startDocument and endDocument events +and then asking those data structures to write themselves out to a +given EventConsumer, or walking data structures (such as JDBC query +results) and applying its own conversion rules. WAP format XML +(WBMXL) can be directly converted to producer output. + +

    SAX2 introduced an "XMLFilter" interface, which is a kind of XMLReader. +It is most useful in conjunction with its XMLFilterImpl helper class; +see the EventFilter javadoc +for information contrasting that XMLFilterImpl approach with the +relevant parts of this pipeline framework. Briefly, such XMLFilterImpl +children can be either producers or consumers, and are more limited in +configuration flexibility. In this framework, the focus of filters is +on the EventConsumer side; see the section on +pipe fitting below. + + +

    Consume to Standard or Custom Data Representations

    + +

    Many consumers will be used to create standard representations of XML +data. The TextConsumer takes its events +and writes them as text for a single XML document, +using an internal XMLWriter. +The DomConsumer takes its events and uses +them to create and populate a DOM Document. + +

    In other cases, you will write consumers yourself. For example, +you might use a particular unmarshaling filter to produce objects +that fit your application's requirements, instead of using DOM. +Such consumers work at the level of XML data models, rather than with +specific representations such as XML text or a DOM tree. You could +convert your output directly to WAP format data (WBXML). + + +

    Pipe Fitting

    + +

    Pipelines are composite event consumers, with each stage having +the opportunity to transform the data before delivering it to any +subsequent stages. + +

    The PipelineFactory class +provides access to much of this functionality through a simple syntax. +See the table in that class's javadoc describing a number of standard +components. Direct API calls are still needed for many of the most +interesting pipeline configurations, including ones leveraging actual +or logical concurrency. + +

    Four basic types of pipe fitting are directly supported. These may +be used to construct complex pipeline networks.

    + +

    Note that filters can be as complex as +XSLT transforms +available) on input data, or as simple as removing simple syntax data +such as ignorable whitespace, comments, and CDATA delimiters. +Some simple "built-in" filters are part of this package. + + +

    Coding Conventions: Filter and Terminus Stages

    + +

    If you follow these coding conventions, your classes may be used +directly (give the full class name) in pipeline descriptions as understood +by the PipelineFactory. There are four constructors the factory may +try to use; in order of decreasing numbers of parameters, these are:

    + +

    Of course, classes may support more than one such usage convention; +if they do, they can automatically be used in multiple modes. If you +try to use a terminus class as a filter, and that terminus has a constructor +with the appropriate number of arguments, it is automatically wrapped in +a "tee" filter. + + +

    Debugging Tip: "Tee" Joints can Snapshot Data

    + +

    It can sometimes be hard to see what's happening, when something +goes wrong. Easily fixed: just snapshot the data. Then you can find +out where things start to go wrong. + +

    If you're using pipeline descriptors so that they're easily +administered, just stick a write ( filename ) +filter into the pipeline at an appropriate point. + +

    Inside your programs, you can do the same thing directly: perhaps +by saving a Writer (perhaps a StringWriter) in a variable, using that +to create a TextConsumer, and making that the first part of a tee -- +splicing that into your pipeline at a convenient location. + +

    You can also use a DomConsumer to buffer the data, but remember +that DOM doesn't save all the information that XML provides, so that DOM +snapshots are relatively low fidelity. They also are substantially more +expensive in terms of memory than a StringWriter holding similar data. + +

    Debugging Tip: Non-XML Producers

    + +

    Producers in pipelines don't need to start from XML +data structures, such as text in XML syntax (likely coming +from some XMLReader that parses XML) or a +DOM representation (perhaps with a +DomParser). + +

    One common type of event producer will instead make +direct calls to SAX event handlers returned from an +EventConsumer. +For example, making ContentHandler.startElement +calls and matching ContentHandler.endElement calls. + +

    Applications making such calls can catch certain +common "syntax errors" by using a +WellFormednessFilter. +That filter will detect (and report) erroneous input data +such as mismatched document, element, or CDATA start/end calls. +Use such a filter near the head of the pipeline that your +producer feeds, at least while debugging, to help ensure that +you're providing legal XML Infoset data. + +

    You can also arrange to validate data on the fly. +For DTD validation, you can configure a +ValidationConsumer +to work as a filter, using any DTD you choose. +Other validation schemes can be handled with other +validation filters. + + diff --git a/libjava/classpath/gnu/xml/stream/AttributeImpl.java b/libjava/classpath/gnu/xml/stream/AttributeImpl.java new file mode 100644 index 000000000..58a0dbe21 --- /dev/null +++ b/libjava/classpath/gnu/xml/stream/AttributeImpl.java @@ -0,0 +1,123 @@ +/* AttributeImpl.java -- + Copyright (C) 2005 Free Software Foundation, Inc. + +This file is part of GNU Classpath. + +GNU Classpath is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 2, or (at your option) +any later version. + +GNU Classpath is distributed in the hope that it will be useful, but +WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
