Checking the actual instance of reference, like "instance of" in Java

Question

Hi All,
I have a method that has the ability to return a number of Z exception class types.  All of these exception classes inherit from the same super Z exception class.  This means that when called the callee only needs to catch the super Z exception class (and pass it on if required). 
However, I would now like to be able to tell which instance it actually is, but only have a reference to the super class.  In Java there is a comparison "instance of" which you can use like an if statement asking if particular reference you have is referening to an instance of a particular class, which you pass to the other side of the if as a string literal.
Does ABAP have a utility class anywhere (as I couldn't find it in the keywords) to do the same thing?
Many thanks,
Alex.

Answer 1

hi, you can try the code like following:
assume C is a class type you defined.
data: B  TYPE REF TO C,
      R  TYPE REF TO OBJECT.
CREATE OBJECT R TYPE C.
R = B.
strname = CL_ABAP_CLASSDESCR=>GET_CLASS_NAME( R ).
you will get a absolute class name of B.
hope it will be helpful
thanks
