Re: NSInvocation question

ents that I wrapped up in NSInvocations. With IMPs, I have to check the number of arguments both for the typing and for the call. However, even with the check for number of arguments, an IMP is very very fast. Thanks! Hank Hank Heijink [EMAIL PROTECTED]

Re: NSInvocation question

ade NSInvocations because timing is critical and I didn't want to spend the time constructing the call when it needs to be invoked. I haven't profiled the difference yet though, so maybe the tradeof isn't bad. I'll give it a whirl. Thanks! Hank Heijink [EMAIL PROTECTED]
