    • getSingleNodePointer

      public Pointer getSingleNodePointer()
      Description copied from class: EvalContext
      Returns the first encountered Pointer that matches the current context's criteria.
      Overrides:
      getSingleNodePointer in class EvalContext
      Returns:
      Pointer

    • getCurrentNodePointer

      public NodePointer 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

    • 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:

      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:
