Modifier and Type	Method and Description
static void	sendWrappedSequence(SequenceIterator iterator, Receiver destination) Take a sequence supplied in the form of an iterator and generate a wrapped represention of the items in the sequence, the wrapped representation being a sequence of events sent to a supplied Receiver.
static void	serialize(NodeInfo node, Result destination, Properties outputProperties, Configuration config) Serialize a document containing wrapped query results (or any other document, in fact) as XML.
static void	serializeSequence(SequenceIterator results, Configuration config, OutputStream destination, Properties outputProps) Serialize an arbitrary sequence, without any special wrapping.
static void	serializeSequence(SequenceIterator results, Configuration config, PrintWriter writer, Properties outputProps) Serialize an arbitrary sequence, without any special wrapping.
static DocumentInfo	wrap(SequenceIterator iterator, Configuration config) Take the results of a query (or any other SequenceIterator) and create an XML document containing copies of all items in the sequence, suitably wrapped

Method Detail

wrap

public static DocumentInfo wrap(SequenceIterator iterator,
                                Configuration config)
                         throws XPathException

Take the results of a query (or any other SequenceIterator) and create an XML document containing copies of all items in the sequence, suitably wrapped

Parameters:

iterator - The values to be wrapped

config - The Saxon configuration used to evaluate the query

Returns:

the document containing the wrapped results

Throws:

XPathException

sendWrappedSequence

public static void sendWrappedSequence(SequenceIterator iterator,
                                       Receiver destination)
                                throws XPathException

Take a sequence supplied in the form of an iterator and generate a wrapped represention of the items in the sequence, the wrapped representation being a sequence of events sent to a supplied Receiver.

Parameters:

iterator - the input sequence

destination - the Receiver to accept the wrapped output

Throws:

XPathException

serialize

public static void serialize(NodeInfo node,
                             Result destination,
                             Properties outputProperties,
                             Configuration config)
                      throws XPathException

Serialize a document containing wrapped query results (or any other document, in fact) as XML.

Parameters:

node - The document or element to be serialized

destination - The Result object to contain the serialized form

outputProperties - Serialization options

config - The Configuration

Throws:

XPathException - If serialization fails

serializeSequence

public static void serializeSequence(SequenceIterator results,
                                     Configuration config,
                                     OutputStream destination,
                                     Properties outputProps)
                              throws XPathException

Serialize an arbitrary sequence, without any special wrapping.

Parameters:

results - the sequence to be serialized

config - the configuration (gives access to information such as the NamePool)

destination - the output stream to which the output is to be written

outputProps - a set of serialization properties as defined in JAXP

Throws:

XPathException - if any failure occurs

serializeSequence

public static void serializeSequence(SequenceIterator results,
                                     Configuration config,
                                     PrintWriter writer,
                                     Properties outputProps)
                              throws XPathException

Serialize an arbitrary sequence, without any special wrapping.

Parameters:

results - the sequence to be serialized

config - the configuration (gives access to information such as the NamePool)

writer - the writer to which the output is to be written

outputProps - a set of serialization properties as defined in JAXP

Throws:

XPathException - if any failure occurs
