• endDocument

  public void endDocument()
                   throws XPathException

  Notify the end of a document node

• endElement

  public void endElement()
                  throws XPathException

  End of element

  Specified by:

  endElement in interface Receiver

  Overrides:

  endElement in class ProxyReceiver

  Throws:

  XPathException

• namespace

  public void namespace​(int namespaceCode,
                        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.

  Specified by:

  namespace in interface Receiver

  Overrides:

  namespace in class ProxyReceiver

  Parameters:

  namespaceCode - an integer: the top half is a prefix code, the bottom half a URI code. These may be translated into an actual prefix and URI using the name pool. A prefix code of zero represents the empty prefix (that is, the default namespace). A URI code of zero represents a URI of "", that is, a namespace undeclaration.

  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: it sets the REJECT_DUPLICATES flag, and this is treated as a hard error.

  Throws:

  XPathException

• open

  public void open()
            throws XPathException

  Start of event stream

  Specified by:

  open in interface Receiver

  Overrides:

  open in class ProxyReceiver

  Throws:

  XPathException

• processingInstruction

  public void processingInstruction​(java.lang.String target,
                                    java.lang.CharSequence data,
                                    int locationId,
                                    int properties)
                             throws XPathException

  Processing Instruction

  Specified by:

  processingInstruction in interface Receiver

  Overrides:

  processingInstruction in class ProxyReceiver

  Parameters:

  target - The PI name. This must be a legal name (it will not be checked).

  data - The data portion of the processing instruction

  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 - Additional information about the PI. The following bits are defined:

  CHECKED

  Data is known to be legal (e.g. doesn't contain "?>")

  Throws:

  XPathException

• 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.

  Specified by:

  startContent in interface Receiver

  Overrides:

  startContent in class ProxyReceiver

  Throws:

  XPathException

• startDocument

  public void startDocument​(int properties)

  Start of a document node.

  Specified by:

  startDocument in interface Receiver

  Overrides:

  startDocument in class ProxyReceiver

  Parameters:

  properties - bit-significant integer indicating properties of the document node. The definitions of the bits are in class ReceiverOptions

  Throws:

  XPathException

• startElement

  public void startElement​(int nameCode,
                           int typeCode,
                           int locationId,

  startElement in interface Receiver

  Overrides:

  startElement in class ProxyReceiver

  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.
