Method Details

getMessageListener

public MessageListener getMessageListener()

Get the wrapped MessageListener

Returns:

the wrapped MessageListener

startDocument

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

public void characters(CharSequence s,
 int locationId,
 int properties)
                throws XPathException

Produce text content output.

Specified by:

characters in interface Receiver

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

Append an item to the sequence, performing any necessary type-checking and conversion

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

Parameters:

item - the item to be written to the sequence

Throws:

XPathException - if any failure occurs while writing the item
