public class UnionSet<E> extends AbstractSet<E>
In order to efficiently provide a union of fewer, larger sets, this provides a
set view on top of other sets. Any set that is added to this union set via
addAll(Set) must not be modified after being added. For
performance purposes, defensive copying is not performed.

Triggers combining.

If the set has size > MAXIMUM_COMBINE_SIZE, the set will be added to the
added list, which may then be later combined only when needed. |
