Hi Nathan, Someone else can correct me if I'm wrong, but after taking a look at the generated code, it seems that virtual methods shouldn't incur any additional performance overhead in GWT. Basically the bottom level method is given the top-level declared name in each object instance, thus the lookup expense is the same as that of a non-virtual method. Like I said, if I'm wrong on this, someone should correct me. ;) Cheers, Jason. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
