Method Summary
void	detach() Detaches the walker from the set which it iterated over, releasing any computational resources and placing the iterator in the INVALID state.
int	getLastPos(XPathContext xctxt) Get the number of nodes in this node list.
boolean	isDocOrdered() Returns true if all the nodes in the iteration well be returned in document order.
boolean	isReverseAxes() Tells if this is a reverse axes.
void	setRoot(int root) Set the root node of the TreeWalker.

Method Detail

detach

getLastPos

public int getLastPos(XPathContext xctxt)

Parameters: xctxt The XPath runtime context.

Returns: the number of nodes in this node list.

isDocOrdered

public boolean isDocOrdered()

Returns true if all the nodes in the iteration well be returned in document order. Warning: This can only be called after setRoot has been called!

Returns: false.

isReverseAxes

public boolean isReverseAxes()

Tells if this is a reverse axes. Overrides AxesWalker#isReverseAxes.

Returns: true for this class.
