Class SynchronizedSortedSet

    java.lang.Object
      org.apache.commons.collections.collection.SynchronizedCollection
          org.apache.commons.collections.set.SynchronizedSortedSet

All Implemented Interfaces:
  java.io.Serializable, java.lang.Iterable, java.util.Collection, java.util.Set, java.util.SortedSet

    public class SynchronizedSortedSet

extends SynchronizedCollection
implements java.util.SortedSet

Decorates another `SortedSet` to synchronize its behaviour for a multi-threaded environment.

Methods are synchronized, then forwarded to the decorated set.

This class is Serializable from Commons Collections 3.1.
