< Ada Programming | Libraries

The Ada package is only an anchor or namespace for Ada's standard library. Most compilers will not allow you to add new packages to the Ada hierarchy and even if your compiler allows it you should not do so since all package names starting with Ada. are reserved for future extensions.

List of implementation defined child units

edit

The Reference Manual allows compiler vendors to add extensions to the Standard Libraries. However, these extensions cannot be directly children of the package Ada, only grandchildren—for example Ada.Characters.Latin_9.

Currently, only the implementation defined library units of the GNAT compiler are listed here. You can help Wikibooks by adding implementation dependent packages of other compilers:

GNAT
Extended package implemented by GNAT.
ObjectAda
Extended package implemented by ObjectAda.
APEX
Extended package implemented by IBM/Rational APEX.
