Get class name without object initialization

former_member275056 — Fri, 01 Jul 2016 13:08:03 GMT

Hi folks,

I'm using RTTS to dynamically get class name for an initialized object. Following codes work just fine:


data obj type ref to zflh_test_class
obj = new #( ).

data cls_descr type ref to cl_abap_classdescr.
cls_descr ?= cl_abap_classdescr=>describe_by_object_ref( obj ).
data(rel_name) = cls_descr->get_relative_name( ). " returns zflh_test_class

The question is: How can I get the class name without object initialization. I would like to have something like this


data obj type ref to zflh_test_class

data cls_descr type ref to cl_abap_classdescr.
cls_descr ?= cl_abap_classdescr=>describe_by_object_ref( obj ).
data(rel_name) = cls_descr->get_relative_name( ).

Of course cl_abap_classdescr=>describe_by_object_ref throws exception because "obj" is initial.

Any idea?

Cheers,

Ferry

Something like that :

DATA obj type ref to if_ixml.
data(ref) = cast cl_abap_refdescr( cl_abap_typedescr=>describe_by_data( obj ) ).
data(objtype) = cast cl_abap_objectdescr( ref->get_referenced_type( ) ).
data(rel_name) = objtype->get_relative_name( ).
ASSERT rel_name = 'IF_IXML'.

It works like a charm. Many thanks for the solution.

Simplifying a bit, we have it:

DATA obj TYPE REF TO if_ixml.
DATA(rel_name) = CAST cl_abap_objectdescr( CAST cl_abap_refdescr( cl_abap_typedescr=>describe_by_data( obj ) )->get_referenced_type( ) )->get_relative_name( ).

ASSERT rel_name = 'IF_IXML'.
