Check for +-- the case where the actual type passed to the formal private extension +-- is a class-wide type. Check for several types in the same class. +-- +-- +-- TEST DESCRIPTION: +-- Declare a list abstraction in a generic package which manages lists of +-- elements of any nonlimited type (foundation code). Declare a package +-- which declares a tagged type and a derivative. Declare an operation +-- for the root tagged type and override it for the derivative. Declare +-- a generic subprogram which operates on lists of elements of tagged +-- types. Provide the generic subprogram with two formal parameters: (1) +-- a formal derived tagged type which represents a list element type, and +-- (2) a generic formal package with the list abstraction package as +-- template. Use the formal derived type as the generic formal actual +-- part for the formal package. Within the generic subprogram, call the +-- operation of the root tagged type. In the main program, instantiate +-- the generic list package and the generic subprogram with the class-wide +-- type for the root tagged type. +-- +-- TEST FILES: +-- The following files comprise this test: +-- +-- FC51D00.A +-- -> CC51D02.A +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 05 Jan 95 SAIC Changed types of TC_Expected_1 and TC_Expected_2 +-- from specific to class-wide.
