Can I actually have recursive objects or just function calls?

>You can have a class tree where Part is the superclass and you derive SimplePart and CompositePart from Part. CompositePart has an aggregation component back to Part. Look at the Composite design pattern.

What about when the composite part has its own subassembly? Take for instance a furniture company that makes kits for assembling an unfinished chair. That part # for the kit would be say kit123. Now lets assume that they also make a finished chair out of the kit. Part number chair456. If they brought up the bom for chair456, would the part# kit123 be a CompositePart? But when they bring up just the bom for kit123, is it now a SimplePart?
