Get the class attributes references dynamically?

Former Member — Mon, 20 Oct 2008 14:28:45 GMT

Hi all,

I have to call a transformation and give it as result parameter an internal table with ABAP_TRANS_RESBIND_TAB type.

How can I get the name & the reference of the current class attributes ?

Thanks.

I am not sure what you want to need, but please check this class CL_ABAP_CLASSDESCR. It may help you.

'ME' refer to current class object.

Here is the solution I wound, but it works with public attributes only!



  DATA: l_typedesc TYPE REF TO cl_abap_typedescr.
  data: l_classdesc TYPE REF TO cl_abap_classdescr.
  data: l_attribute TYPE abap_attrdescr.
  data : att_ref type ref to any.
  FIELD-SYMBOLS : <att> TYPE ANY . "abap_attrname.
  DATA : name TYPE string.

  CLEAR st_root_out.
  CALL METHOD cl_abap_classdescr=>describe_by_object_ref 
  EXPORTING
  p_object_ref = me
  RECEIVING
  p_descr_ref = l_typedesc.

  l_classdesc ?= l_typedesc.

  LOOP AT l_classdesc->attributes INTO l_attribute "-
  WHERE type_kind = cl_abap_classdescr=>typekind_string "-
  OR type_kind = cl_abap_classdescr=>typekind_num "-
  OR type_kind = cl_abap_classdescr=>typekind_date "-
  OR type_kind = cl_abap_classdescr=>typekind_packed "-
  OR type_kind = cl_abap_classdescr=>typekind_time "-
  OR type_kind = cl_abap_classdescr=>typekind_char "-
  OR type_kind = cl_abap_classdescr=>typekind_hex "-
  OR type_kind = cl_abap_classdescr=>typekind_float "-
  OR type_kind = cl_abap_classdescr=>typekind_int "-
  OR type_kind = cl_abap_classdescr=>typekind_table "-
  OR type_kind = cl_abap_classdescr=>typekind_struct2 "-
  OR type_kind = cl_abap_classdescr=>typekind_struct1 "-
  OR type_kind = cl_abap_classdescr=>typekind_oref
  OR type_kind = cl_abap_classdescr=>typekind_time. "-

    name = l_attribute-name .

    ASSIGN me->(name) TO <att>.

    CHECK sy-subrc = 0.

    GET REFERENCE OF <att> INTO att_ref. " here I get the reference



  
  ENDLOOP.
