Interface method Signature...

[Former Member]

Hi all,

Is there any Function Module that can be used to modify

the signature of a method in an interface from code??

I want to write a FM that imports the interface and

method name and changes the method signature..

Pls Help.

Thanks in advance.

I don't understand what you try to do.

Signature of a method cannot be changed. What you have to do is to create a new method with new signature.

Here is a sample program which will give you thep signature of the class/methods. I'm not sure how to update them, or if it is a good idea to do so.

report zrich_0003.


data: l_dref  type ref to cl_abap_typedescr.
data: l_clref  type ref to cl_abap_classdescr.
data: x_methods type abap_methdescr.
data: x_parameters type abap_parmdescr.

constants: query_class type seoclsname
                    value 'CL_GUI_ALV_GRID'.

* check if query_class exists in the current system
call method cl_abap_classdescr=>describe_by_name
  exporting
    p_name         = query_class
  receiving
      p_descr_ref = l_dref
  exceptions
    type_not_found = 1
    others         = 2.
if sy-subrc <> 0.
  exit.
endif.

l_clref ?= l_dref.

loop at l_clref->methods into x_methods.

  write:/ x_methods-name.

  loop at x_methods-parameters into x_parameters.
    write:/     x_parameters-length,
        x_parameters-decimals,
        x_parameters-type_kind,
        x_parameters-name,
        x_parameters-parm_kind     .

  endloop.

  skip 3.


endloop.
