In the latter case, ensure that the primitive +-- equality operation of the record extension compares any extended +-- components according to the predefined equality operators of the +-- component types. Also check that the parent portion of the extended +-- type is compared using the user-defined equality operation of the +-- parent type. +-- +-- TEST DESCRIPTION: +-- Declares a nonlimited tagged record and a limited tagged record +-- type, each in a separate package. A user-defined "=" operation is +-- defined for each type. Each type is extended with one new record +-- component added. +-- +-- Objects are declared for each parent and extended types and are +-- assigned values. For the limited type, modifier operations defined +-- in the package are used to assign values. +-- +-- To verify the use of the user-defined "=", values are assigned so +-- that predefined equality will return the opposite result if called. +-- Similarly, values are assigned to the extended type objects so that +-- one comparison will verify that the inherited components from the +-- parent are compared using the user-defined equality operation. +-- +-- A second comparison sets the values of the inherited components to +-- be the same so that equality based on the extended component may be +-- verified. For the nonlimited type, the test for equality should +-- fail, as the "=" defined for this type should include testing +-- equality of the extended component. For the limited type, "=" of the +-- parent should be inherited as-is, so the test for equality should +-- succeed even though the records differ in the extended component. +-- +-- A third package declares a discriminated tagged record. Equality +-- is user-defined and ignores the discriminant value. A type +-- extension is declared which also contains a discriminant. Since +-- an inherited discriminant may not be referenced other than in a +-- "new" discriminant, the type extension is also discriminated. The +-- discriminant is used as the constraint for the parent type. +-- +-- A variant part is declared in the type extension based on the new +-- discriminant. Comparisons are made to confirm that the user-defined +-- equality operator is used to compare values of the type extension. +-- Two record objects are given values so that user-defined equality +-- for the parent portion of the record succeeds, but the variant +-- parts in the type extended object differ. These objects are checked +-- to ensure that they are not equal. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 19 Dec 94 SAIC Removed RM references from objective text. +-- +--! + +with Ada.Calendar; +package C340001_0 is + + type DB_Record is tagged record + Key : Natural range 1 .. 9999; + Data : String (1..10); + end record; + + function "=" (L, R : in DB_Record) return Boolean; + + type Dated_Record is new DB_Record with record + Retrieval_Time : Ada.Calendar.Time; + end record; + +end C340001_0; + +package body C340001_0 is + + function "=" (L, R : in DB_Record) return Boolean is + -- Key is ignored in determining equality of records + begin + return L.Data = R.Data; + end "="; + +end C340001_0; + +package C340001_1 is + + type List_Contents is array (1..10) of Integer; + type List is tagged limited record + Length : Natural range 0..10 := 0; + Contents : List_Contents := (others => 0); + end record; + + procedure Add_To (L : in out List; New_Value : in Integer); + procedure Remove_From (L : in out List); + + function "=" (L, R : in List) return Boolean; + + subtype Revision_Mark is Character range 'A' ..
