public class TByteSetDecorator
extends java.util.AbstractSet<java.lang.Byte>
implements java.util.Set<java.lang.Byte>, java.io.Externalizable

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