Class ProxiedSet<E>

java.lang.Object

de.larssh.utils.collection.ProxiedCollection<E>

de.larssh.utils.collection.ProxiedSet<E>

Type Parameters:

E - the type of elements in this set

All Implemented Interfaces:

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

public abstract class ProxiedSet<E>
extends ProxiedCollection<E>
implements Set<E>

An abstract Set implementation pointing to a given set object.

Therefore it allows implementing sets based on invisible set types, such as Collections.unmodifiableSet(Set) or Collections.synchronizedSet(Set).
