java.lang.Object

de.caff.generics.AbstractBasicCountingSet<T>

de.caff.generics.CountingHashSet<T>

All Implemented Interfaces:

CountingSet<T>, java.lang.Iterable<T>, java.util.Collection<T>, java.util.Set<T>

public class CountingHashSet<T>
extends AbstractBasicCountingSet<T>

A set which also counts how often any element was added.

Because it would be breaking the set semantics removal is not allowed. All removal methods but AbstractBasicCountingSet.clear() therefore will throw an UnsupportedOperationException.
