I need a mixture between XSEQUENCE and CSEQUENCE

rainer_hbenthal — Wed, 19 Nov 2008 11:36:08 GMT

Hi,

i would like to have a method which accepts XSEQUENCE or CSEQUENCE or to be more exact it should axxept XSTRING or STRING.

The only type i can see which covers that is ANY. But how to react if a structure or a table is delivered? I would like to raise an exception.

So, how can i check if the type is string or xstring?

Hi Rainer,

There might be some other simple way..... but one way is to use RTTI service...

example - an exception is triggered if passed data obj is not of elementary type.

DATA : gv_string   TYPE string,
       gv_xstring  TYPE xstring,
       gs_struc    TYPE makt,
       gt_table    TYPE TABLE OF makt,
       go_data_ref TYPE REF TO cl_abap_elemdescr.

TRY.
    go_data_ref ?= cl_abap_typedescr=>describe_by_data( gv_string ).     " safe
    go_data_ref ?= cl_abap_typedescr=>describe_by_data( gv_xstring ).    " safe
    go_data_ref ?= cl_abap_typedescr=>describe_by_data( gs_struc ).      " triggers exception
    go_data_ref ?= cl_abap_typedescr=>describe_by_data( gt_table ).      " triggers exception
  CATCH cx_sy_move_cast_error.
    BREAK-POINT.  " it is a struc or table
ENDTRY.

Cheers,

Jose.

Hi Jose,

the solution was rather simple

i'm now using data type simple which only allows flat data types plus string and xstring.

Inside the method i'm checking the type with old fashioned describe statement.
