    • Method Detail

      • getTentativeContent

        public java.util.List<OutputterEvent> getTentativeContent()

      • isEmpty

        public boolean isEmpty()

      • open

        public void open​(Terminator terminator)
          throws XPathException
        Open the watch. This is done at the point where it first starts watching for nodes that match the selection.
        Overrides:
        open in class ItemFeed
        Parameters:
        terminator - used for early exit
        Throws:
        XPathException - if a dynamic error occurs

      • close

        public void close()
           throws XPathException
        The close() method is called immediately before the Watch is destroyed, that is, when the element whose declaration scopes the constraint implemented by this Watch goes out of scope. The default implementation does nothing.
        Specified by:
        close in interface Receiver
        Overrides:
        close in class ItemFeed
        Throws:
        XPathException - if a dynamic error occurs

      • startSelectedParentNode

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

      • endSelectedParentNode

        public void endSelectedParentNode​(Location locationId)
                           throws XPathException
        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

        Parameters:
        elemName - the name of the element.
        typeCode - the type annotation of the element.
        location - an object providing information about the module, line, and column where the node originated
        properties - bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in class ReceiverOption
        Throws:
        XPathException - if an error occurs

      • startElement

        public void startElement​(NodeName elemName,
                         SchemaType type,
                         AttributeMap attributes,

                  throws XPathException
        Description copied from class: ProxyOutputter
        Notify the start of an element, supplying all attributes and namespaces
        Specified by:
        startElement in interface Receiver
        Overrides:
        startElement in class ProxyOutputter
        Parameters:
        elemName - the name of the element.
        type - the type annotation of the element.
        attributes - the attributes of this element
        namespaces - the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elements
        location - an object providing information about the module, line, and column where the node originated
        properties - bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in class ReceiverOption
        Throws:
        XPathException - if an error occurs

      • namespace

        public void namespace​(java.lang.String prefix,
                      java.lang.String namespaceUri,
                      int properties)
               throws XPathException
        Description copied from class: ProxyOutputter
        Notify a namespace binding. This method is called at some point after startElement(). The semantics are similar to the xsl:namespace instruction in XSLT, or the namespace node constructor in XQuery. A namespace must not conflict with any namespaces already used for element or attribute names.
        Overrides:
        namespace in class ProxyOutputter
        Parameters:
        prefix - The namespace prefix; zero-length string for the default namespace
        namespaceUri - The namespace URI. In some cases a zero-length string may be used to indicate a namespace undeclaration.
        properties - The REJECT_DUPLICATES property: if set, the namespace declaration will be rejected if it conflicts with a previous declaration of the same prefix. If the property is not set, the namespace declaration will be ignored if it conflicts with a previous declaration. This reflects the fact that when copying a tree, namespaces for child elements are emitted before the namespaces of their parent element. Unfortunately this conflicts with the XSLT rule for complex content construction, where the recovery action in the event of conflicts is to take the namespace that comes last. XSLT therefore doesn't recover from this error:
        Throws:
        XPathException - if an error occurs

      • characters

        public void characters​(java.lang.CharSequence chars,
                       Location location,
                       int properties)
                throws XPathException
        Description copied from class: ProxyOutputter
        Notify character data. Note that some receivers may require the character data to be sent in a single event, but in general this is not a requirement.
        Specified by:
        characters in interface Receiver
        Overrides:
        characters in class ProxyOutputter
        Parameters:
        chars - The characters

        DISABLE_ESCAPING
        Disable escaping for this text node
        USE_CDATA
        Output as a CDATA section
        Throws:
        XPathException - if an error occurs
