The Storage_IO subprograms, Read and Write, +-- demonstrated in this scenario, perform tag "fixing" prior to/following +-- transfer to the Direct_IO files. +-- This method is especially important for those implementations that +-- represent tags as pointers, or for cases where the tagged objects +-- are read in by a program other than the one that wrote them. +-- +-- In this small example, we have attempted to simulate the situation +-- where two independent programs are using a series of Direct_IO files, +-- one writing data to the files, and the second program reading the +-- data from those files. Two procedures are defined, the first +-- simulating the program responsible for writing, the second simulating +-- a separate program opening and reading the data from the files. +-- +-- The hierarchy of types used in this test can be displayed as follows: +-- +-- Account_Type +-- / \ +-- / \ +-- / \ +-- Cash_Account_Type Investment_Account_Type +-- / \ +-- / \ +-- / \ +-- Checking_Account_Type Savings_Account_Type +-- +-- APPLICABILITY CRITERIA: +-- Applicable to implementations capable of supporting external +-- Direct_IO files. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 08 Nov 95 SAIC Corrected incorrect prefix of 'Tag for ACVC 2.0.1, +-- and mode of files in Procedure Read_Data. +-- Added verification of objects reconstructed from +-- files. +-- 27 Feb 97 PWB.CTA Allowed for non-support of some IO operations +--! + +package CXA9002_0 is + + type Investment_Type is (Stocks, Bonds, Mutual_Funds); + type Savings_Type is (Standard, Business, Impound); + + type Account_Type is tagged + record + Num : String (1..3); + end record; + + type Cash_Account_Type is new Account_Type with + record + Years_As_Customer : Natural := 1; + end record; + + type Investment_Account_Type is new Account_Type with + record + Investment_Vehicle : Investment_Type := Stocks; + end record; + + type Checking_Account_Type is new Cash_Account_Type with + record + Checks_Per_Year : Positive := 200; + Interest_Bearing : Boolean := False; + end record; + + type Savings_Account_Type is new Cash_Account_Type with + record + Kind : Savings_Type := Standard; + end record; + +end CXA9002_0; + +--- + +with Report; +with Ada.Storage_IO; +with Ada.Direct_IO; +with Ada.Tags; +with CXA9002_0; + +procedure CXA9002 is + package Dir_IO is new Ada.Direct_IO (Integer); + Test_File : Dir_IO.File_Type; + Incomplete : exception; +begin + + Report.Test ("CXA9002", "Check that the operations defined in the " & + "generic package Ada.Storage_IO provide the " & + "ability to store and retrieve objects of " & + "tagged types from in-memory buffers"); + + + Test_For_Direct_IO_Support: + begin + + -- The following Create does not have any bearing on the test scenario, + -- but is included to check that the implementation supports Direct_IO + -- files.
