All Implemented Interfaces:

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

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

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