By making -- this public release, the Government intends to confer upon all -- recipients unlimited rights equal to those held by the Government. -- These rights include rights to use, duplicate, release or disclose the -- released technical data and computer software in whole or in part, in -- any manner and for any purpose whatsoever, and to have or permit others -- to do so. -- -- DISCLAIMER -- -- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR -- DISCLOSED ARE AS IS.

Declare a new primitive subprogram for the extension, -- and override one of the two inherited subprograms. Within the -- overriding subprogram, utilize type conversion to call the parent's -- implementation of the same subprogram. Also within the overriding -- subprogram, call the new primitive subprogram and each inherited -- subprogram. -- -- Extend the extension with a record extension in the same package -- specification. Declare a new primitive subprogram for this second -- extension, and override one of the three inherited subprograms. -- Within the overriding subprogram, utilize type conversion to call the -- parent's implementation of the same subprogram. Also within the -- overriding subprogram, call the new primitive subprogram and each -- inherited subprogram. -- -- In the main program, declare objects of the root tagged type -- and the two type extensions. For each object, call the overriding -- subprogram, and verify the correctness of the components by using -- aggregates and equality operators, or by checking the components -- directly. -- -- TEST FILES: -- This test consists of the following files: -- -- F390A00.A -- C390A010.A -- => C390A011.AM -- -- -- CHANGE HISTORY: -- 06 Dec 94 SAIC ACVC 2.0 -- 04 Jun 96 SAIC ACVC 2.1: Modified prologue. -- --! with Report; with F390A00; -- Basic alert abstraction. with C390A010; -- Extended alert abstraction. use F390A00; -- Primitive operations of Alert_Type directly visible. with Ada.Calendar; procedure C390A011 is use type Ada.Calendar.Time; -- Equality/inequality ops directly visible. begin Report.Test ("C390A01", "Primitive operation inheritance by type " & "extensions: all extensions declared in same package, " & "but a different package from that of root type"); ALERT_SUBTEST: ------------------------------------------------------------- declare Alarm : F390A00.Alert_Type; -- Root tagged type. begin -- Check "/=" operator availability.
