Best way to check if a file matches an ignore pattern

Hi,

I want to add a feature to my Eclipse plugin so that when you add create
a new file in Eclipse that is inside a Bazaar branch and that file does
not match an ignore pattern then it will automatically be added to
Bazaar (this will be a preference option).

How can I check if a file matches an ignore pattern? I could parse the
.bzrignore files myself and reimplement Bazaar's logic in Java but would
rather not do that (also if bzr implements this differently I will have
to change my code).

I could also use bzr ls --ignored and see if the file is listed in the
output but I'm wondering if there is a better way?

What I would like is a "should-be-ignored" command that returns an exit
code that indicates this....
