INTERFACE intf
Other versions: 7.31 | 7.40 | 7.54
Syntax
INTERFACE intf [PUBLIC].
[components]
ENDINTERFACE.
Addition
Effect
The statement block INTERFACE - ENDINTERFACE defines an
interface intf.
Naming conventions apply to the name intf.
The components of the interface are declared between INTERFACE and ENDINTERFACE.
An interface defined using INTERFACE can be implemented in classes and included
in other interfaces using the statement INTERFACES.
Addition
... PUBLIC
Effect
The addition PUBLIC makes the interface intf a
global interface of the class library. The addition PUBLIC can only be used for the global interface of an
interface pool and is created by
Class Builder when a global interface is created .
Note
A global interface is a global object type and is in the same namespace as a global class and as the global data types in ABAP Dictionary.
Example
In this example, an interface i1 is declared using three interface components
a1, m1, and e1. The class c1 implements the interface and the interface components therefore become
public components of the class, which can be addressed using the interface component selector (~).
INTERFACE i1.
DATA a1 TYPE string.
METHODS m1.
EVENTS e1 EXPORTING value(p1) TYPE string.
ENDINTERFACE.
CLASS c1 DEFINITION.
PUBLIC SECTION.
INTERFACES i1.
ENDCLASS.
CLASS c1 IMPLEMENTATION.
METHOD i1~m1.
RAISE EVENT i1~e1 EXPORTING p1 = i1~a1.
ENDMETHOD.
ENDCLASS.
