Check for +-- the case where the actual type passed to the formal private extension +-- is a specific tagged 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 type derived from it. Declare an +-- operation for the root tagged type and override it for the derived +-- type. Derive a type from this derived type, but do not override the +-- operation. 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 root tagged type and each derivative, then call +-- each instance with an object of the appropriate type. +-- +-- TEST FILES: +-- The following files comprise this test: +-- +-- FC51D00.A +-- -> CC51D01.A +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 04 Jan 95 SAIC Moved declaration of type Ranked_ID_Type from +-- main subprogram to package CC51D01_0.
