Implicit character or charactered structure --> to String Conversion

Former Member — Mon, 20 Jul 2009 10:26:57 GMT

Hi everybody,

that sounds trivial but i am struggeling.... which is the most elegant way to do a implicit "To-String" Conversion in ABAP Objects...

I have e.g.

data lok_string type string.

lok_string = wa.

m_object->addline( lok_string ).

which is working fine but is not elegant comaring with java.

i want

m_object->addline( wa ).

but this don't go when "wa" is a structured workarea with many "type c"s in it (and only these).

but since the explicit assignment "lok_string = wa." is working well, there could be a elegant implicit one?

(m_object->addline expects a string variable.)

Thank is aprreciated.

Regards

Hartmut

We can't understand. You must have forgotten something...

sorry, I am getting more clear now, i am searching a conversion method which converts data from a character-structured workarea to a string, and which i can use as a functional method (say as part of an expression), for that i can ommit the help variables in the example above.

something like that ?


class lcl_xxx definition.
  public SECTION.
    class-methods addline IMPORTING charlike TYPE clike RETURNING VALUE(string) TYPE string.
endclass.
class lcl_xxx IMPLEMENTATION.
  method addline.
    string = charlike.
  endmethod.
endclass.
start-of-SELECTION.
data a type bapireturn.
data b type string.

b = lcl_xxx=>addline( charlike = a ).

Hi Sandra,

this is the right direction.... but i would like to have it as an nested expression... (since implicit conversion seams to be impossible)

like...

m_object->addline( lcl_xxx=>tostring( wa_head ) )

but this line above is not an valid abap objects syntax, unfortunatelly

... having:

class lcl_xxx definition.

public section.

class-methods tostring importing charlike type clike returning value(string) type string.

endclass.

class lcl_xxx implementation.

method tostring.

string = charlike.

endmethod.

endclass.

Best regards

Unfortunately, we must define intermediate variables. Be patient, nested functions will be available from release 7.10 (or 7.0 from unknown EHP)
