Subject [jira] Commented: (COLLECTIONS-306) Use Predicate in subtract
Date Tue, 09 Dec 2008 09:11:44 GMT


Henri Yandell commented on COLLECTIONS-306:

I'm missing something here - I don't see where the b list is used in your proposed method.

It looks like you only use it in the Predicate itself and the commented out filter method
is cleaner.

> It is good idea to use Predicate in subtract method, I've developed myself the mentioned
method and now I am testing it. I mean we should have following methods:
