Check that the formal type may be further extended with a +-- private extension in the generic package. +-- +-- Check that the (visible) components inherited by the "generic" +-- extension are visible outside the generic package. +-- +-- Check that, in the instance, the private extension inherits the +-- user-defined primitive subprograms of the tagged actual, including +-- those inherited by the actual from its parent. +-- +-- TEST DESCRIPTION: +-- Declare a tagged type and an associated primitive subprogram in a +-- package specification (foundation code). Declare a private extension +-- of the tagged type and an associated primitive subprogram in a second +-- package specification. Declare a generic package which takes a tagged +-- type as a formal parameter, and then extends it with a private +-- extension (foundation code). +-- +-- Instantiate the generic package with the private extension from the +-- second package (the "generic" extension should now have inherited +-- the primitive subprograms of the private extension from the second +-- package). +-- +-- In the main program, call the primitive subprograms inherited by the +-- "generic" extension. There are two: (1) Create_Book, declared for +-- the root tagged type in the first package (inherited by the private +-- extension of the second package, and then in turn by the "generic" +-- extension), and (2) Update_Pages, declared for the private extension +-- in the second package. Verify the correctness of the components. +-- +-- TEST FILES: +-- The following files comprise this test: +-- +-- F730A000.A +-- F730A001.A +-- => C730A02.A +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + +with F730A001; -- Book definitions. +package C730A02_0 is -- Extended book abstraction. + + + type Detailed_Book_Type is new F730A001.Book_Type -- Private ext. + with private; -- of root tagged + -- type. + + -- Inherits Create_Book from Book_Type. + + procedure Update_Pages (Book : in out Detailed_Book_Type; -- Primitive op. + Pages : in Natural); -- of extension. + + + -- The following function is needed to verify the value of the + -- extension's private component.
