gnu.trove.decorator.TDoubleHashSetDecorator

All Implemented Interfaces:: Externalizable, Serializable, Iterable<Double>, Collection<Double>, Set<Double>

public class TDoubleHashSetDecorator extends AbstractSet<Double> implements Set<Double>, Externalizable

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.
