public final class SAX2DTM2.ParentIterator

extends DTMDefaultBaseIterators.InternalAxisIteratorBase

Iterator that returns the parent of a given node. Note that this delivers only a single node; if you want all the ancestors, see AncestorIterator.

Method Summary

int	next() Get the next node in the iteration.
DTMAxisIterator	setNodeType(int type) Set the node type of the parent that we're looking for.

public SAX2DTM2.ParentIterator()

Method Detail

setStartNode

public DTMAxisIterator setStartNode(int node)

Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

Parameters:

node - Sets the root of the iteration.

Returns:

A DTMAxisIterator set to the start of the iteration.

setNodeType

public DTMAxisIterator setNodeType(int type)

Set the node type of the parent that we're looking for. Note that this does _not_ mean "find the nearest ancestor of this type", but "yield the parent if it is of this type".

Parameters:

type - extended type ID.

Returns:

ParentIterator configured with the type filter set.

next

public int next()

Get the next node in the iteration. In this case, we return only the immediate parent, _if_ it matches the requested nodeType.

Returns:

The next node handle in the iteration, or END.
