All Implemented Interfaces:

Collection, Serializable, Set

Direct Known Subclasses:

SynchronizedSortedSet

public class SynchronizedSet

extends SynchronizedCollection

implements Set

The SynchronizedSet class is used to synchronize all operations on a Set object on a particular object.

Each method of this implementation synchronizes on a specified object specified at construction time, and then calls the method of the same signature of the backing set. Each instance is serializable only if the backing set and mutex is serializable.

This is similar to the synchronization methods in Collections, but this implementation allows you to choose what object to synchronize on, and allows subclassing.
