Christopher Schultz updated VELOCITY-533:
-----------------------------------------
Attachment: PrimitiveArrayWrapper.java
Per discussion on the developer list, I am including a class that can wrap a
primitive array (any array, actually) and provide collection-like access to it.
Requires Java 1.2 or better since it uses the Java Collections API.
> Treat arrays like fixed-length lists

> I'd like to see arrays treated like fixed-length List objects as much as
> possible. This means auto-magically supporting size(), set(int,Object),
> get(int), and isEmpty() at a minimum. Support for something like iterator()
> probably isn't necessary, since #foreach already handles arrays, but it might
> be good for completeness. These should be possible via some Uberspect
> hackery.
> And since the goal is to free template authors from having to care about the
> differences between Lists and arrays, we might also consider supporting
> conversion between the two for method calls, so:
> $foo.wantsListHere($thisisAnArray)
> and
> $bar.wantsArrayHere($thisisAList)
> both work automatically. I haven't yet looked into what it would take to do
> this. If it is too hard or messy, i could be happy with just support for
> calling List methods on arrays.
