using class's methods

Former Member — Wed, 31 Jan 2007 11:59:32 GMT

Dear All,

I have a question related to using a method of a class with parameters.

What is wrong with my code ?

DATA ref_Var TYPE REF TO CL_ABAP_STRING_UTILITIES.

Data sour(5) type c value 'First'.

Data dest type string.

CL_ABAP_STRING_UTILITIES->C2STR_PRESERVING_BLANKS( sour dest ).

Regards

Ilhan

It should be = not -

CL_ABAP_STRING_UTILITIES=>C2STR_PRESERVING_BLANKS( sour dest ).

and the code should be

call method CL_ABAP_STRING_UTILITIES=>C2STR_PRESERVING_BLANKS

exporting

source = source

importing

DEST = dest.

dest = CL_ABAP_STRING_UTILITIES=>C2STR_PRESERVING_BLANKS( sour ).

Regards,

Ravi

Hi Ertas,

If CL_ABAP_STRING_UTILITIES is a static class then use

CL_ABAP_STRING_UTILITIES=>C2STR_PRESERVING_BLANKS

otherwise

create object and call like this

ref_var->C2STR_PRESERVING_BLANKS

Hi Ilhan,

Try this code:

report ZRTTEST .

Data sour(5) type c value 'First'.

Data dest type string.

call method CL_ABAP_STRING_UTILITIES=>C2STR_PRESERVING_BLANKS

exporting

source = sour

importing

DEST = dest.

write: dest.

hello,

call method is running but the second way with

dest = CL_ABAP_STRING_UTILITIES=>C2STR_PRESERVING_BLANKS( sour ).

returns the error message:

C2STR_PRESERVING_BLANKS does not have a Returning Parameter.

You can not use it in expressions.

Does it mean the second way is worng or is there onother alternative.

Hi Ilhan,

What the error message says is right. You cannot use the second code. Sorry for that. It should have a return parameter instead of the exporting parameter to use it that way. YOu have to use it the other way only.

Ravi
