public class VersionIteratorImpl

extends Object

implements VersionIterator

This Class implements a VersionIterator that iterates over a version graph following the successor nodes. When this iterator is created, it gathers the id's of the versions and returns them when iterating. please note, that a version can be deleted while traversing this iterator and the 'nextVesion' would produce a ConcurrentModificationException.

VersionIteratorImpl(Session session, InternalVersion rootVersion)
Creates a new VersionIterator that iterates over the version tree, starting the root node.

Method Summary

long	getPosition()
long	getSize()
boolean	hasNext()
Object	next()
