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.
