this is called model chaining. where models know that their model
object is another model and can properly handle it.
in this particular example
imodel d=getdefaultmodel()
imodel p=new propertymodel(d, "multiply")
p.getobject() then does this
object target=mytarget; (in this case d)
while (target instanceof imodel) { target=imodel.getobject(); }
getproperty(target, property);
so in execution p.getobject() resolves to this: d.getobject().getmultiply();
makes sense?
