All Implemented Interfaces:

Enumeration

public class DynamicEnumeration
extends Object
implements Enumeration

A dynamic Enumeration which allows items to added to the enumeration while it is in use. This is mostly intended for use with SequenceInputStream.

This class is entirely thread safe. Attempting to use the enumeration and to add objects from a single thread is not recommended, as it may deadlock the thread.
