      public void startDocument(int properties) throws XPathException
      Start of a document node.
      Specified by:
      startDocument in interface Receiver
      Overrides:
      startDocument in class SequenceWriter
      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
    • startElement

      public void startElement(NodeName nameCode, SchemaType typeCode, int locationId, int properties) throws XPathException
      Output an element start tag.
      Specified by:
      startElement in interface Receiver
      Overrides:
      startElement in class SequenceWriter
      Parameters:
      nameCode - The element name code - a code held in the Name Pool
      typeCode - Integer code identifying the type of this element. Zero identifies the default type, that is xs:anyType
      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 flags indicating any special information
      Throws:
      XPathException - if an error occurs
    • characters

      Overrides:
      characters in class SequenceWriter
      Parameters:
      s - The String to be output
      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 flags for extra information, e.g. disable-output-escaping
      Throws:
      XPathException - for any failure
    • append

      public void append(Item item, int locationId, int copyNamespaces) throws XPathException

      Overrides:
      append in class SequenceWriter
      Parameters:
      item - the item to be appended
      locationId - the location of the calling instruction, for diagnostics
      copyNamespaces - if the item is an element node, this indicates whether its namespaces need to be copied. Values are NodeInfo.ALL_NAMESPACES, NodeInfo.LOCAL_NAMESPACES, NodeInfo.NO_NAMESPACES
      Throws:
      XPathException - if the operation fails
    • write

      public void write(Item item) throws XPathException
      Abstract method to be supplied by subclasses: output one item in the sequence.
      Specified by:
      write in class SequenceWriter
