Class Serializer

class Serializer extends Object implements Destination

A Serializer takes a tree representation of XML and turns it into lexical XML markup.

Note that this is XML serialization in the sense of the W3C XSLT and XQuery specifications. This has nothing to do with the serialization of Java objects, or the java.io.Serializable interface.

The serialization may be influenced by a number of serialization parameters. A parameter has a name, which is an instance of Property, and a value, which is expressed as a string. The effect of most of the properties is as described in the W3C specification XSLT 2.0 and XQuery 1.0 Serialization. Saxon supports all the serialization parameters defined in that specification, together with some additional parameters, whose property names are prefixed "SAXON_".

Serialization parameters defined via this interface take precedence over any serialization parameters defined within the source of the query or stylesheet.

Method Detail

close

public void close()
Close any resources associated with this destination

getOutputDestination

public Object getOutputDestination()
Get the current output destination.

Returns: an OutputStream, Writer, or File, depending on the previous calls to Serializer, Serializer, or Serializer

getOutputProperty

public String getOutputProperty(Serializer.Property property)
Get the value of a serialization property

Parameters: property the name of the required property

Returns: the value of the required property as a string, or null if the property has not been given any value.

getReceiver

public Receiver getReceiver(Configuration config)
Return a receiver to which Saxon will send events. This method is provided primarily for system use, though it could also be called by user applications wanting to make use of the Saxon serializer.

Parameters: config The Saxon configuration. This is an internal implementation object held within the Processor

Returns: a receiver to which XML events will be sent

getReceiver

protected Receiver getReceiver(Configuration config, Controller controller, Properties predefinedProperties)
Return a receiver to which Saxon will send events. This method is provided primarily for system use, though it could also be called by user applications wanting to make use of the Saxon serializer.

Parameters: config The Saxon configuration controller The Saxon controller for the transformation or query. May be null if unknown. predefinedProperties values of serialization properties defined within a query or stylesheet, which will be used in the event that no value for the corresponding property has been defined in the Serializer itself. May be null if no serialization properties have been predefined.

Returns: a receiver to which XML events will be sent

setOutputFile

public void setOutputFile(File file)
Set the destination of the serialized output, as a File.

Calling this method has the side-effect of setting the current OutputWriter and OutputStream to null.

Parameters: file the File to which the serialized XML output will be written.

setOutputProperty

public void setOutputProperty(Serializer.Property property, String value)
Set the value of a serialization property. Any existing value of the property is overridden. If the supplied value is null, any existing value of the property is removed.

Example:

serializer.setOutputProperty(Serializer.Property.METHOD, "xml");

Any serialization properties supplied via this interface take precedence over serialization properties defined in the source stylesheet or query.

Parameters: property The name of the property to be set value The value of the property, as a string. The format is generally as defined in the xsl:output declaration in XSLT: this means that boolean properties, for example, are represented using the strings "yes" and "no". Properties whose values are QNames, such as cdata-section-elements are expressed using the Clark representation of a QName, that is "{uri}local". Multi-valued properties (again, cdata-section-elements is an example) are expressed as a space-separated list.

Throws: IllegalArgumentException if the value of the property is invalid. The property is validated individually; invalid combinations of properties will be detected only when the properties are actually used to serialize an XML event stream.

setOutputStream

public void setOutputStream(OutputStream stream)
Set the destination of the serialized output, as an OutputStream.

Closing the output stream after use is the responsibility of the caller.

Calling this method has the side-effect of setting the OutputWriter and OutputFile to null.

Parameters: stream the OutputStream to which the serialized XML output will be written.

setOutputWriter

public void setOutputWriter(Writer writer)
Set the destination of the serialized output, as a Writer.

Note that when this option is used, the serializer does not perform character encoding. This also means that it never replaces special characters with XML numeric character references. The final encoding is the responsibility of the supplied Writer.

Closing the writer after use is the responsibility of the caller.

Calling this method has the side-effect of setting the OutputStream and OutputFile to null.

Parameters: writer the Writer to which the serialized XML output will be written.
