ABAP INTERFACE DEFINITION Statement syntax, information and example SAP source code

INTERFACE intf

Short Reference

ABAP Syntax INTERFACE intf [PUBLIC].
[ components ]
ENDINTERFACE.

ABAP_ADDITION:
... PUBLIC

What does it do? 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 .
Latest notes: The definition of an interface can only be specifed in the context described under INTERFACE .

ABAP_ADDITION ... PUBLIC

What does it do? If you use the PUBLIC addition, the interface
ifac becomes a global interface of the class library. The PUBLIC
addition can only be used for the global interface of an interface pool and is generated by the
Class Builder when a global interface is created.

Example ABAP Coding 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.
