-- OBJECTIVE:
|
27 |
|
|
-- Check that the functionality found in packages Ada.Strings.Wide_Maps,
|
28 |
|
|
-- Ada.Strings.Wide_Fixed, and Ada.Strings.Wide_Maps.Wide_Constants

|
-- TEST DESCRIPTION:
|
32 |
|
|
-- This test validates the subprograms found in the various Wide_Map
|
33 |
|
|
-- and Wide_String packages. It is based on the tests CXA4024 and
|
34 |
|
|
-- CXA4026, which are tests for the complementary "non-wide" packages.
|
35 |
|
|
--
|
36 |
|
|
-- The functions found in CXA4025_0 provide mapping capability, when
|
37 |
|
|
-- used in conjunction with Wide_Character_Mapping_Function objects.
