ABAPTYPES_REF_TO_INCLUDE - TYPES REF TO INCLUDE
Vendor Master (General Section) rdisp/max_wprun_time - Maximum work process run timeThis documentation is copyright by SAP AG.
Effect
The data type type is declared as a reference in
ABAP Objects. cif is either a
class or an
interface. References are used to type reference variables which, in turn, contain references (pointers) to
objects.
References that refer to a class
are called class references. Likewise, references that refer to an interface are called interface references.
Reference variables which are typed using class references can contain object references to objects
of that class. Reference variables which are typed using interface references can contain object references to objects whose class implements the interface.
Note
Objects, that is, instances of classes are only addressed using reference variables. For creating objects, see CREATE OBJECT.
Example
INTERFACE I1.
METHODS M1.
ENDINTERFACE.
CLASS C1 DEFINITION.
PUBLIC SECTION.
INTERFACES I1.
ENDCLASS.
TYPES: T_C1 TYPE REF TO C1,
T_I1 TYPE REF TO I1.
DATA: O1 TYPE T_C1,
O2 LIKE O1,
IR TYPE T_I1.
CREATE OBJECT O1.
O2 = O1.
IR = O1.
CLASS C1 IMPLEMENTATION.
METHOD I1~M1.
...
ENDMETHOD.
ENDCLASS.
