Class Component Selector

A static component comp of a class can be accessed using the following name:

class=>comp

In this case, no instance of the class needs to be created. The characters => are the class component selector. The name class of a class must be on the left of the class component selector. The name comp of the component must be on the right of the class component selector.

The class component selector can also be used to access the data types and constants of an interface:

intf=>type, intf=>const

The name intf of an interface must be on the left of the class component sector. The name type of a data type defined using TYPES or the name const of a constant defined using CONSTANTS must be on the right of the object component selector.

Other versions: 7.31 | 7.40 | 7.54

Note

It is also possible to access the static components of a class using the object component selector if an instance of the class was created.

Example

Declares a class factory and accesses its static attribute oref.

CLASS factory DEFINITION CREATE PRIVATE. 
  PUBLIC SECTION. 
    CLASS-DATA oref TYPE REF TO factory. 
    CLASS-METHODS class_constructor. 
    METHODS do_something. 
ENDCLASS. 

... 

factory=>oref->do_something( ). 

... 

CLASS factory IMPLEMENTATION. 
  METHOD class_constructor. 
    CREATE OBJECT oref. 
  ENDMETHOD. 
  METHOD do_something. 
    ... 
  ENDMETHOD. 
ENDCLASS.
