Meta class equivalent?

[Former Member]

Hi there,

Is there a meta-class equivalent in ABAP Objects?

I know I can execute methods (static or otherwise) dynamically if I know the names involved (names of class/object, method, parameters, etc).

But if I don't know all names, how can I find them dynamically? For instance, if I know static method "CREATE_CAKE" from class "CL_CAKE_FACTORY", can I know at run time which parameters I can use (if any)?

Best Regards,

Paulo

Hello Paulo

The way how to dynamically execute CALL METHOD is described in the ABAP keywords help.

CALL METHOD (meth_name) 

Syntax 
CALL METHOD dynamic_meth { parameter_list 
                         | parameter_tables }. 

Effect 
This statement calls the method dynamically specified in dynamic_meth.
Actual parameters are assigned to formal parameters without parentheses,
either statically using parameter_list or dynamically using parameter_tables.
The syntax of parameter_list is the same as that for the static method call. 
...

In order to get the signature of methods you can use class CL_OO_CLASS.

Hi there,

CL_OO_CLASS was just what I was looking for.

Thanks,
