Is there in SAP something similar to instanceof in Java ?

Thanks

Check this. It is not directly built-in to the language, but you can acheive the same with a little coding.

report ztest.

*---------------------------------------------------------------------*
*       CLASS lcl_app DEFINITION
*---------------------------------------------------------------------*
*       ........                                                      *
*---------------------------------------------------------------------*
class lcl_app definition.

  public section.
    data: field type string.

endclass.

*---------------------------------------------------------------------*
*       CLASS lcl_app IMPLEMENTATION
*---------------------------------------------------------------------*
*       ........                                                      *
*---------------------------------------------------------------------*
class lcl_app implementation.


endclass.

data: o_ref type ref to cl_abap_classdescr,
      o_object type ref to object.

create object o_object type lcl_app.

o_ref ?= cl_abap_typedescr=>describe_by_name( 'LCL_APP' ).

if  o_ref->applies_to( o_object ) = 'X'.
  write / 'This Object is an instance of the class'.
else.
  write / 'This Object is NOT an instance of the class'.
endif.

Hello Ariana

Please have a look at the static method <b>CL_WDY_WB_REFLECTION_HELPER=>IS_INSTANCE_OF</b> (available on 6.40).

Please DONOT use class CL_WDY_WB_REFLECTION_HELPER. It is NOT released for public use. At least with higher levels of release or support package any use will violate package restrictions.

Klaus
