Classes and Interfaces
This section describes the definition of classes and
interfaces and of their
components . Classes and interfaces
form the basis for ABAP Objects , the
object-oriented part of the ABAP language. Classes and interfaces can be
defined in ABAP programs of the following
program types :
In a class pool , you use the
Class Builder tool of the
ABAP Workbench to define exactly one
global class of the class library, which can then be used in all other
ABAP programs. In the global declaration section of a class pool, you
can individually define local data types, classes and interfaces to be
used in the class pool and make type groups
known.
In an interface pool , you use the
Class Builder tool of the ABAP Workbench to define exactly one global
interface of the class library to be used in all other ABAP programs. In
the global declaration section of an interface pool, you are not allowed
to define local data types, classes and interfaces. You can declare type
groups. In interface pools, no other statements are allowed outside of
the global interfaces.
In all other ABAP programs, except type groups, you can define local
classes and interfaces to be used in the program itself.
