AbsoluteIterator

public final class AbsoluteIterator extends DTMAxisIteratorBase
Absolute iterators ignore the node that is passed to setStartNode(). Instead, they always start from the root node. The node passed to setStartNode() is not totally useless, though. It is needed to obtain the DOM mask, i.e. the index into the MultiDOM table that corresponds to the DOM "owning" the node. The DOM mask is cached, so successive calls to setStartNode() passing nodes from other DOMs will have no effect (i.e. this iterator cannot migrate between DOMs).
