    • open

      public void open() throws XPathException
      Open the event stream
      Specified by:
      open in interface Receiver
      Overrides:
      open in class Builder
      Throws:
      XPathException
    • startDocument

      public void startDocument(int properties) throws XPathException
      Write a document node to the tree
      Specified by:
      startDocument in interface Receiver
      Overrides:
      startDocument in class Builder
      Parameters:
      properties - bit-significant integer indicating properties of the document node. The definitions of the bits are in class ReceiverOptions
      Throws:
      XPathException
    • endDocument

      public void endDocument() throws XPathException
      Callback interface for SAX: not for application use
      Specified by:
      endDocument in interface Receiver
      Overrides:
      endDocument in class Builder
      Throws:
      XPathException
    • reset

      public void reset()
      Description copied from class: Builder
      Reset the builder to its initial state. The most important effect of calling this method (implemented in subclasses) is to release any links to the constructed document tree, allowing the memory occupied by the tree to released by the garbage collector even if the Builder is still in memory. This can happen because the Builder is referenced from a parser in the Configuration's parser pool.
      Overrides:
      reset in class Builder
    • close

      public void close() throws XPathException
      Description copied from interface: Receiver
      Notify the end of the event stream
      Specified by:
      close in interface Receiver
      Overrides:
      close in class Builder
      Throws:
      XPathException
    • startElement

      public void startElement(int nameCode, int typeCode, int locationId, int properties) throws XPathException
      Notify the start tag 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. The value -1 indicates the default type, xs:untyped.
      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 properties of the element node. If there are no revelant properties, zero is supplied. The definitions of the bits are in class ReceiverOptions
      Throws:
      XPathException
    • namespace

      public void namespace(int namespaceCode, int properties) throws XPathException
      Description copied from interface: Receiver
      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. The events represent namespace declarations and undeclarations rather than in-scope namespace nodes: an undeclaration is represented by a namespace code of zero. If the sequence of namespace events contains two A namespace must not conflict with any namespaces already used for element or attribute names.
      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
    • attribute

      public void attribute(int nameCode, int typeCode, CharSequence value, int locationId, int properties) throws XPathException
      Description copied from interface: Receiver
      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. The additional bit NodeInfo.IS_DTD_TYPE may be set to indicate a DTD-derived type.
      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.
      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
      Throws:
      XPathException
    • startContent

      public void startContent()
      Description copied from interface: Receiver
      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.
    • endElement

      public void endElement() throws XPathException
      Callback interface for SAX: not for application use
      Throws:
      XPathException
    • getLastCompletedElement

      public NodeInfo getLastCompletedElement()
      Get the last completed element node. This is used during checking of schema assertions, which happens while the tree is still under construction. This method is called immediately after a call on endElement(), and it returns the element that has just ended.
      Returns:
      the last completed element node, that is, the element whose endElement event is the most recent endElement event to be reported
    • characters

      public void characters(CharSequence chars, int locationId, int properties) throws XPathException
      Callback interface for SAX: not for application use
      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
      Throws:
      XPathException
    • processingInstruction

      public void processingInstruction(String piname, CharSequence remainder, int locationId, int properties) throws XPathException
      Callback interface for SAX: not for application use
      Parameters:
      piname - The PI name. This must be a legal name (it will not be checked).
      remainder - 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
    • comment

      public void comment(CharSequence chars, int locationId, int properties) throws XPathException
      Callback interface for SAX: not for application use
      Parameters:

      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 comment. The following bits are defined:
      CHECKED
      Comment is known to be legal (e.g. doesn't contain "--")
