Class TIntSetDecorator

java.lang.Object

java.util.AbstractCollection<Integer>

java.util.AbstractSet<Integer>

gnu.trove.decorator.TIntSetDecorator

All Implemented Interfaces:

Externalizable, Serializable, Iterable<Integer>, Collection<Integer>, Set<Integer>

public class TIntSetDecorator
extends AbstractSet<Integer>
implements Set<Integer>, Externalizable

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