      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.

      public boolean isReverseAxes()
      Tells if this is a reverse axes. Overrides AxesWalker#isReverseAxes.
      Overrides:
      isReverseAxes in class PredicatedNodeTest
      Returns:
      true for this class.

    • getLastPos

      public int getLastPos(XPathContext xctxt)
      Get the number of nodes in this node list. The function is probably ill named?
      Specified by:
      getLastPos in interface SubContextList
      Overrides:
      getLastPos in class AxesWalker
      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 class AxesWalker
      Returns:
