C++ Scripting: Part 24 – Default Parameters

Tags: , , , , ,

We’ve been able to call methods since the very beginning, but we’ve always had to pass all the parameters. Today we’ll add support for default parameters so you can skip them sometimes. There’s a surprising amount of detail involved with this, so read on to learn some caveats of C#, .NET, and C++.

While I was working on last week’s article it became apparent that something strange was going on with the arguments keyword in AS3. Last week I showed that even after you’ve changed the parameters of a function, you can still get the original values by indexing into arguments. This implies a copy and a copy implies a slowdown. Read on to see if there really is a slowdown and, if there is, what kind of performance impact there is.

Var Args Is Slow

Tags: ,

Var args (a.k.a. …rest) is a useful feature introduced in AS3. Previously in AS2 (and JavaScript still), we were forced to pass an Array of arguments where an unlimited-length argument list would have been much natural. Unfortunately, this can be really slow. In this article I’ll show a much quicker way to pass unlimited arguments to functions.
