hyyy guys,

How to translate ABAP method in .net , if I make function and return of object class.

etc ;

public AbstractClass CreateSomething()

{

return new ClassA();

}

I just know that ABAP use CREATE OBJECT <cref>, but that method require

reference variable. How can I solve the problem?

Thanks

Hi there,

Consider the following scenario.. In the class definition you specify what the return type is in exporting parameter (in this case we have some class defined as 'lcl_abstract' as an example).

CLASS lcl_test DEFINITION.
  PUBLIC SECTION.
    METHODS: createsomething
    EXPORTING my_obj TYPE REF TO lcl_abstract.
ENDCLASS.        

CLASS lcl_test IMPLEMENTATION.
  METHOD: createsomething.
    CREATE OBJECT my_obj.
  ENDMETHOD.                 
ENDCLASS.      

------------------------------

DATA: obj_ref TYPE REF TO lcl_abstract,
          test_ref TYPE REF TO lcl_test.

START-OF-SELECTION.

CREATE OBJECT test_ref.

test_ref->createsomething( importing my_obj = obj_ref ).

Hi,

have a look at this code. The method createsomething now has a returning parameter + you can see how you to use the word TYPE to actually specify the concrete class which inherits from the abstract class.


CLASS lcl_test DEFINITION.
  PUBLIC SECTION.
    METHODS: createsomething RETURNING VALUE(my_obj) TYPE REF TO lcl_abstract.
ENDCLASS.        
 
CLASS lcl_test IMPLEMENTATION.
  METHOD: createsomething.
    CREATE OBJECT my_obj type ClassA.
  ENDMETHOD.                 
ENDCLASS.

cheers
