  • Field Details

    • startedSet

      private boolean startedSet

    • nodeSet

      private NodeSet nodeSet

  • Constructor Details

    • NodeSetContext

      public NodeSetContext(EvalContext parentContext, NodeSet nodeSet)
      Create a new NodeSetContext.
      Parameters:
      parentContext - parent context
      nodeSet - associated NodeSet

  • Method Details

    • getNodeSet

      public NodeSet getNodeSet()
      Description copied from class: EvalContext
      Returns the list of all Pointers in this context for all positions of the parent contexts. If there was an ongoing iteration over this context, the method should not be called.
      Overrides:
      getNodeSet in class EvalContext
      Returns:
      NodeSet

    • 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

    • 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

    • 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
