  • Field Details

    • started

      private boolean started

    • collection

      private boolean collection

    • nodePointer

      private NodePointer nodePointer

  • Constructor Details

    • InitialContext

      public InitialContext(EvalContext parentContext)
      Create a new InitialContext.
      Parameters:
      parentContext - parent context

  • Method Details

    • 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

    • getValue

      public Object getValue()
      Description copied from class: EvalContext
      Typically returns the NodeSet by calling getNodeSet(), but will be overridden for contexts that more naturally produce individual values, e.g. VariableContext
      Overrides:
      getValue in class EvalContext
      Returns:
      Object

    • 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

    • 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

    • nextSet

      public boolean nextSet()
      Description copied from class: EvalContext
      Returns true if there is another sets of objects to interate over. Resets the current position and node.
      Overrides:
      nextSet in class EvalContext
      Returns:
      boolean
