Method Detail

getNodes

public void getNodes(XPathNode contextNode,
                     NodeTest nodeTest,
                     XMutableNodeSet result)

Get the nodes of the axis, filtered by the NodeTest.

Overrides:

getNodes in class Axis

Parameters:

contextNode - the context node

nodeTest - the node test

result - a nodeset for the matching nodes.

getModelWalker

public ModelWalker getModelWalker()

Return this.

Specified by:

getModelWalker in class Axis

getProximityModelWalker

public ModelWalker getProximityModelWalker()

Return this.

Overrides:

getProximityModelWalker in class Axis

gotoFirstNode

public XPathNode gotoFirstNode(XPathNode contextNode)

Return the getStartNode(contextNode).

Specified by:

gotoFirstNode in interface ModelWalker

Returns:

the first node of the path represented by this ModelWalker.- If null the path is empty.

gotoNextNode

public XPathNode gotoNextNode(XPathNode lastNode)

Return the parent.

Specified by:

gotoNextNode in interface ModelWalker

Parameters:

lastNode - a XPathNode obtained from the last call to gotoFirstNode or gotoNextNode. If the node is another node the behaviour is not determined.

Returns:

the next node of the path represented by this ModelWalker.- If null then the path ended.

getStartNode

protected XPathNode getStartNode(XPathNode contextNode)
