Predicate collections.

[Peter Veentjer]

Maybe it would be an idea to add predicate collections, so a simple predicate can be added to a collection to check the validity of the new element.

interface Predicate<T>{
     boolean valid(T item).
}

And maybe it would be an idea to add a null rejecting predicate.

I have written 'ncollections' These are null rejecting predicate collection with the advantage that you have a new type: NList, NCollection, NSet etc. Now you can force someone to use a specific kind of collection. I only don`t have the time to maintain it ;)

Good suggestion.
I will implement it.

Just released jaxlib-0.3.1
The package jaxlib.col.filtered implements predicated collections. Just named it "filtered" to be coherent with package jaxlib.closure.
