Class ChainedIterator<E>

java.lang.Object
  org.mmbase.util.ChainedIterator<E>

All Implemented Interfaces:

Iterator<E>

public class ChainedIterator<E>
extends Object
implements Iterator<E>

Like org.apache.commons.collections.iterators.IteratorChain, to avoid the dependency.... It is quite easy to understand what this actually is. It is an Iterator implemetnation which is based on other Iterators. During iterating, it simply iterates them all sequentially.

MMBase-1.8
