    - #### NoCloseFeed

          public NoCloseFeed​(ItemFeed parentFeed,
                             XPathContext context)

  - ### Method Detail

    - #### open

          public void open​(Terminator terminator)
                    throws XPathException

      Description copied from class: `ItemFeed`
      Start evaluating the expression. The default implementation does nothing.
      Overrides:
        `open` in class `ItemFeed`
      Parameters:
        `terminator` - used to achieve early exit
      Throws:
        `XPathException` - if a dynamic error occurs

    - #### startSelectedParentNode

          public Receiver startSelectedParentNode​(FleetingParentNode node,
                                                  Location locationId)
                                           throws XPathException

      Description copied from class: `ItemFeed`
      Signal that an element or document node has been found that matches the selection that this Watch is looking for. This method is called by the WatchManager while processing the startElement or startDocument event that matches the selection.
      Overrides:
        `startSelectedParentNode` in class `ItemFeed`
      Parameters:
        `node` - the element or document node whose start event has been matched
        `locationId` - the location associated with the element or document node (may be the location of the instruction that created it)
      Returns:
        a Receiver to be notified of all events starting with the startElement/startDocument event for the matched element, and ending with the endElement event for that element; or null if this feature is not required.
      Throws:
        `XPathException` - May be raised if a dynamic error occurs

    - #### append

          public void append​(Item item)
                      throws XPathException

      Description copied from class: `ItemFeed`
      Supply one item towards the streamed input of the expression
      Specified by:
        `append` in interface `Receiver`
      Specified by:
        `append` in class `ItemFeed`
      Parameters:
        `item` - the item to be supplied
      Throws:
        `XPathException` - if the operation fails

    - #### endSelectedParentNode

          public void endSelectedParentNode​(Location locationId)
                                     throws XPathException

      Description copied from class: `ItemFeed`
      Signal that the endElement event has occurred for the element whose startElement event caused the Watch to be activated.
      Overrides:
        `endSelectedParentNode` in class `ItemFeed`
      Parameters:
        `locationId` - the location of the element
      Throws:
        `XPathException` - May be raised if a constraint implemented by this Watch is violated

    - #### close

          public void close()

      Description copied from class: `ItemFeed`
      Finish evaluating the expression.
      Specified by:
        `close` in interface `Receiver`
      Overrides:
