Class ReducedSet<E>

java.lang.Object
  org.omnaest.utils.structure.collection.set.ReducedSet<E>

Type Parameters:

E -

All Implemented Interfaces:

Serializable, Iterable<E>, Collection<E>, Set<E>

public class ReducedSet<E>
extends Object
implements Set<E>, Serializable

A ReducedSet acts like the underlying Set but with removed elements of a second Set.

This Set does perform the delta analysis for each method call once again, which makes it very costly to use.
