Interacting with a Base Class
« on: December 09, 2005, 08:12:03 am »
What is the best way, using a sequence diagram, to show how overrided members interact between the derived class and the base class.  Since the 2 classes are still only a single instance should there only be one lifeline??

Self-calls???


























ObjX------------------------>MyObject:
MyParent
        |                 |---------
        |         ||base.overriddenMethod()
        |         |<---------


Not that thats very clear though.

Perhaps a <<virtual>> object for the base? Any takers?

I also noticed when I drag a class onto a sequence diagram that one of the options is to drop it "As New Child (Generalization)".  This almost sounds like what I may want to do.  But this menu option is always grayed out when I try to drop the class on a sequence diagrams.  ANyone know what this option is for or how to use it?
