[antlist] custom task - how to pass *.java filenames

[T Master]

I'm starting to write my own custom task (oooooh) as a wrapper around
JavaNCSS.

I want to be able to pass all the *.java names to my task.
I'm thinking I should have my custom task allow a nested fileset (along with
patternset).

How would I pass this to my task?  Would it be a String[] of the actual
*.java filenames?

All comments appreciated, and thanks in advance.
