  • Method Details

    • getNodePointer

      public NodePointer getNodePointer()
      Description copied from interface: NodeIterator
      Get the NodePointer at the current position.
      Specified by:
      getNodePointer in interface NodeIterator
      Returns:
      NodePointer
    • getPosition

      public int getPosition()
      Description copied from interface: NodeIterator
      Get the current iterator position.
      Specified by:
      getPosition in interface NodeIterator
      Returns:
      int position
    • setPosition

      public boolean setPosition(int position)
      Description copied from interface: NodeIterator
      Set the new current position.
      Specified by:
      setPosition in interface NodeIterator
      Parameters:
      position - the position to set
      Returns:
      true if there is a node at position.
    • previous

      private boolean previous()
      This is actually never invoked during the normal evaluation of xpaths - an iterator is always going forward, never backwards. So, this is implemented only for completeness and perhaps for those who use these iterators outside of XPath evaluation.
      Returns:
      boolean
    • next

      private boolean next()
      Iterate to next pointer.
      Returns:
      whether valid
    • testChild

      private boolean testChild()
      Test a child node.
      Returns:
      whether test passes.
