java.util.AbstractSet<T>

com.ibm.wala.util.collections.ArraySet<T>

All Implemented Interfaces:

Serializable, Iterable<T>, Collection<T>, Set<T>

public class ArraySet<T>
extends AbstractSet<T>
implements Serializable

A set implementation backed by an array. This implementation is space-efficient for small sets, but several operations like contains(Object) are linear time.
