  • Constructor Details

    • DescendantContext

      public DescendantContext(EvalContext parentContext, boolean includeSelf, NodeTest nodeTest)
      Constructs a new DescendantContext.
      Parameters:
      parentContext - parent context
      includeSelf - whether to include this node
      nodeTest - test
  • Method Details

    • getCurrentNodePointer

      Description copied from class: EvalContext
      Returns the current context node. Undefined before the beginning of the iteration.
      Specified by:
      getCurrentNodePointer in class EvalContext
      Returns:
      NodePoiner
    • isChildOrderingRequired

      public boolean isChildOrderingRequired()
      Description copied from class: EvalContext
      Even if this context has the natural ordering and therefore does not require collecting and sorting all nodes prior to returning them, such operation may be required for any child context.
      Overrides:
      isChildOrderingRequired in class EvalContext
      Returns:
      boolean
    • nextNode

      public boolean nextNode()
      Description copied from class: EvalContext
      Returns true if there is another object in the current set. Switches the current position and node to the next object.
      Specified by:
      nextNode in class EvalContext
      Returns:
      boolean
    • reset

      public void reset()
      Description copied from class: EvalContext
      Sets current position = 0, which is the pre-iteration state.
      Overrides:
      reset in class EvalContext
    • setPosition

      public boolean setPosition(int position)
      Description copied from class: EvalContext
      Moves the current position to the specified index. Used with integer predicates to quickly get to the n'th element of the node set. Returns false if the position is out of the node set range. You can call it with 0 as the position argument to restart the iteration.
      Overrides:
      setPosition in class EvalContext
      Parameters:
      position - to set
      Returns:
      boolean
