Using Predicate

[Carlos Chavez <ca...@gmail.com>]

Hello people,

I have a collection where each items is a array of object( object[] ),
I want to use UniquePredicate to filter each item based on two items in the
array (object[])

But, i can't figure out how the UniquePredicate work. the docs says:
Evaluates the predicate returning true if the input object hasn't been
received yet.
I want to extend this for my object[], but i don't know at wich moment this
predicate indicate that the element exist in the collection.

any help are welcome.

Cheers.

Your problems may be due to the fact that two arrays with the same 
contents are not equal (the equals() method doesn't return true). This 
is a historic oddity in Java.

If you change each of your collection elements to be a List instead of 
an array I expect that the predicate would work.
