Class AbstractLazyIterator<T>

java.lang.Object

org.apache.jackrabbit.commons.iterator.AbstractLazyIterator<T>

All Implemented Interfaces:

Iterator<T>

public abstract class AbstractLazyIterator<T>
extends Object
implements Iterator<T>

AbstractLazyIterator provides basic iteration methods for a lazy loading iterator that does not support remove. Implementing classes only need to implement the getNext() method which must return the next item in the iteration or null if the iteration as reached its end.
