  org.hibernate.util.JoinedIterator

All Implemented Interfaces:

java.util.Iterator

public class JoinedIterator
extends java.lang.Object
implements java.util.Iterator

An JoinedIterator is an Iterator that wraps a number of Iterators. This class makes multiple iterators look like one to the caller. When any method from the Iterator interface is called, the JoinedIterator will delegate to a single underlying Iterator. The JoinedIterator will invoke the Iterators in sequence until all Iterators are exhausted.
