Casting c to string in a methode calling

Torsten_ — Mon, 14 May 2007 12:41:41 GMT

Hallo,

I've a methode with a string paramter like: code]methode(i_param TYPE string)[/code].

In the calling methode the parameter value

l_value

for i_param is stored in a variable from type c.

In java I would like call:

methode((string) l_value)

(For all java guys: I know that casting between basic types and objects are not possible, but I belive string isn't an object in ABAP)

Is there any simular way in ABAP or is this me way:

         DATA: l_value_string TYPE string. 
         MOVE l_value TO l_value_string. 
         methode( l_value_string ).

Hi Torsten,

There is no other way as far as I know...Might be in release 7.10, but I have no info about it.

Casting exist also in ABAP, but only for objects:

DATA: dref1 TYPE REF TO i, 
      dref2 TYPE REF TO data. 

CREATE DATA dref1. 
dref2 = dref1. 
CREATE DATA dref2 TYPE string. 

TRY. 
  dref1 ?= dref2. 
  CATCH cx_sy_move_cast_error. 
  ... 
ENDTRY.

I agree, that it would be quite useful.

Best regards,

Peter

Hello Torsten

If you are already working on SAP release 6.20 or higher then you can use static method <b>CL_ABAP_CONTAINER_UTILITIES=>FILL_CONTAINER_C</b>.
