INTERFACE intf

Short Reference

Other versions: 7.31 | 7.40 | 7.54

Syntax


INTERFACE intf [PUBLIC]. 
  [components]
ENDINTERFACE.

Addition

... PUBLIC

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.


Note

The definition of an interface can only be specifed in the context described under INTERFACE.

Addition

... PUBLIC

Effect

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

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.
