public class TLongSetDecorator
extends java.util.AbstractSet<java.lang.Long>
implements java.util.Set<java.lang.Long>, java.io.Externalizable

Wrapper class to make a TLongSet conform to the java.util.Set API. This class simply decorates an underlying TLongSet 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.
