Troubles with If...

[jaminben]

Hello,

I've been trying to use the Utility If call to determine if an object is a MediaObject or not. The java docs quite clearly states that:

Returns the second argument if the first argument is true, otherwise the third argument is returned. All 3 arguments will be evaluated in all cases. This does NOT have a short-circuit which prevents evaluation of the third argument if the first is true.

Is there an equivalent call that will provide a short-circuit so it doesn't evaluate the third argument if the first is true?

Cheers

Ben

Edit:

Never mind we got around it another way.

By definition, a method call always evaluates all of its arguments, before the method itself is invoked. So no, there's no way to write an If() method that doesn't do that; it's a fundamental part of the language, not a quirk of that particular method. The only way to avoid evaluation is to use the Conditional widget control stucture to skip over whole lines of code.

Ahhh, thanks for the explanation......I did wonder but now I know for sure
