Method Details
-
setRoot
public void setRoot(int root) Set the root node of the TreeWalker. (Not part of the DOM2 TreeWalker interface).- Overrides:
setRoot
in classAxesWalker
- Parameters:
root
- The context node of this step.
-
detach
public void detach()Detaches the walker from the set which it iterated over, releasing any computational resources and placing the iterator in the INVALID state.- Overrides:
detach
in classAxesWalker
-
isReverseAxes
public boolean isReverseAxes()Tells if this is a reverse axes. Overrides AxesWalker#isReverseAxes.- Overrides:
isReverseAxes
in classPredicatedNodeTest
- Returns:
- true for this class.
-
getLastPos
Get the number of nodes in this node list. The function is probably ill named?- Specified by:
getLastPos
in interfaceSubContextList
- Overrides:
getLastPos
in classAxesWalker
- 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!- Overrides:
isDocOrdered
in classAxesWalker
- Returns:
- false.
