      • startDocument

        public void startDocument​(int properties)
                           throws XPathException
        Start of a document node.
        Parameters:
        properties - bit-significant integer indicating properties of the document node. The definitions of the bits are in class ReceiverOptions
        Throws:
        XPathException - if an error occurs
      • endDocument

        public void endDocument()
                         throws XPathException
        Notify the end of a document node
        Throws:
        XPathException - if an error occurs
      • startElement

        public void startElement​(NodeName nameCode,
                                 SchemaType typeCode,
                                 int locationId,
                                 int properties)
                          throws XPathException
        Notify the start of an element
        Parameters:
        nameCode - integer code identifying the name of the element within the name pool.
        typeCode - integer code identifying the element's type within the name pool.
        properties - for future use. Should be set to zero.
        locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
        Throws:
        XPathException - if an error occurs
      • namespace

        public void namespace​(NamespaceBinding namespaceBinding,
                              int properties)
                       throws XPathException
        Notify a namespace. Namespaces are notified after the startElement event, and before any children for the element. The namespaces that are reported are only required to include those that are different from the parent element; however, duplicates may be reported. A namespace must not conflict with any namespaces already used for element or attribute names.
        Parameters:
        namespaceBinding - the prefix/uri pair representing the namespace binding to be written
        properties - The most important property is REJECT_DUPLICATES. If this property is 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
      • attribute

        public void attribute​(NodeName nameCode,
                              SimpleType typeCode,
                              java.lang.CharSequence value,
                              int locationId,
                              int properties)
                       throws XPathException
        Notify an attribute. Attributes are notified after the startElement event, and before any children. Namespaces and attributes may be intermingled.
        Parameters:
        nameCode - The name of the attribute, as held in the name pool
        typeCode - The type of the attribute, as held in the name pool
        properties - Bit significant value. The following bits are defined:
        DISABLE_ESCAPING
        Disable escaping for this attribute
        NO_SPECIAL_CHARACTERS
        Attribute value contains no special characters
        value - the string value of the attribute
        locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
        Throws:
        XPathException - if an error occurs
      • startContent

        public void startContent()
                          throws XPathException
        Notify the start of the content, that is, the completion of all attributes and namespaces. Note that the initial receiver of output from XSLT instructions will not receive this event, it has to detect it itself. Note that this event is reported for every element even if it has no attributes, no namespaces, and no content.
        Throws:
        XPathException - if an error occurs
      • characters

        public void characters​(java.lang.CharSequence chars,
                               int locationId,

                        throws XPathException
        Character data
        Parameters:
        chars - The characters
        locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
        properties - Bit significant value. The following bits are defined:
        DISABLE_ESCAPING
        Disable escaping for this text node
        USE_CDATA
        Output as a CDATA section

                                          int properties)

        Overrides:
        setUnparsedEntity in class SequenceReceiver
        Parameters:

      • usesTypeAnnotations

        public boolean usesTypeAnnotations()
        Ask whether this Receiver (or the downstream pipeline) makes any use of the type annotations supplied on element and attribute events
        Returns:
        true if the Receiver makes any use of this information. If false, the caller may supply untyped nodes instead of supplying the type annotation
