java.util.AbstractCollection<E>

java.util.AbstractSet

gnu.trove.decorator.TDoubleHashSetDecorator

All Implemented Interfaces:

java.lang.Iterable, java.util.Collection, java.util.Set

public class TDoubleHashSetDecorator
extends java.util.AbstractSet
implements java.util.Set

Wrapper class to make a TDoubleHashSet conform to the java.util.Set API. This class simply decorates an underlying TDoubleHashSet and translates the Object-based APIs into their Trove primitive analogs.

Note that wrapping and unwrapping primitive values is extremely inefficient. If possible, users of this class should override the appropriate methods in this class and use a table of canonical values.
