<div>Hi,</div> <div> </div> <div> By creating a new class and mentioning the super class will achieve the functionality of Delegation? I feel if the Business object is having a delegation then the event of the delegation will be executed. How about in the case of ABAP OOPS. If I am having a new logic for the std method in the subclass. How will this subclass is called?</div> <div> </div> <div> </div> <div>Thanks</div> <div>Raghavendra<BR><BR><B><I>"Dart, Jocelyn" <jocelyn.dart@sap.com></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">Mike, <BR>The equivalent of "Create subtype" for ABAP OO classes, is to create your class and then in the Properties tab nominate your Superclass.<BR><BR>Delegation is unnecessary because narrowing/widening cast means you can move between parent and child freely.<BR>Regards,<BR>Jocelyn <BR><BR>________________________________<BR><BR>From:
