predicatedSet
public static Set predicatedSet(Set set,
Predicate predicate) Returns a predicated set backed by the given set. Only objects
that pass the test in the given predicate can be added to the set.
It is important not to use the original set after invoking this
method, as it is a backdoor for adding unvalidated objects.
set - the set to predicate, must not be nullpredicate - the predicate for the set, must not be null
- a predicated set backed by the given set
predicatedSortedSet
public static SortedSet predicatedSortedSet(SortedSet set,
Predicate predicate) Returns a predicated sorted set backed by the given sorted set.
Only objects that pass the test in the given predicate can be added
to the sorted set.
It is important not to use the original sorted set after invoking this
method, as it is a backdoor for adding unvalidated objects.
