    • getSequenceNr

      public int getSequenceNr()
      Get the sequence number of this item within a set of items representing nested nodes
      Returns:
      the sequence number

    • getGatherer

      public abstract Receiver getGatherer() throws XPathException
      Get a receiver which will be notified of all events in the streamed input between the start event for this node and the corresponding end event. This Receiver gathers data into the pending item so that the final result of processing the streamed node can be computed by the deliver() method
      Returns:
      a receiver to be notified of all events relating to this streamed input node
      Throws:
      XPathException - if a dynamic error is detected

    • deliver

      public abstract Sequence deliver() throws XPathException
      On completion of this streamed node, that is, when the relevant end tag is reached, compute the result of processing this node and return this result
      Returns:
      the result of processing a streamed input node
      Throws:
      XPathException - if the processing fails with a dynamic error

    • rollback

      public abstract void rollback()
      Reset the data relating to this node if a dynamic error occurs while processing the input stream.
