public class SerializerFactory
extends Object
implements Serializable

Helper class to construct a serialization pipeline for a given result destination and a given set of output properties. The pipeline is represented by a Receiver object to which result tree events are sent. Since Saxon 8.8 is is possible to write a subclass of SerializerFactory and register it with the Configuration, allowing customisation of the Serializer pipeline. The class includes methods for instantiating each of the components used on the Serialization pipeline. This allows a customized SerializerFactory to replace any or all of these components by subclasses that refine the behaviour.

SerializerFactory

public SerializerFactory(Configuration config)

Create a SerializerFactory

Parameters:

config - the Saxon Configuration

Method Detail

getXMLStreamWriter

public XMLStreamWriter getXMLStreamWriter(StreamResult result,
                                          Properties properties)
                                   throws XPathException

Create a serializer with given output properties, and return an XMLStreamWriter that can be used to feed events to the serializer.

Parameters:

result - the destination of the serialized output (wraps a Writer, an OutputStream, or a File)

properties - the serialization properties to be used

Returns:

a serializer in the form of an XMLStreamWriter

Throws:

XPathException - if any error occurs

getReceiver

public Receiver getReceiver(Result result,
                            PipelineConfiguration pipe,
                            Properties props)
                     throws XPathException

Get a Receiver that wraps a given Result object. Saxon calls this method to construct a serialization pipeline. The method can be overridden in a subclass; alternatively, the subclass can override the various methods used to instantiate components of the serialization pipeline.

Note that this method ignores the SaxonOutputKeys.WRAP output property. If wrapped output is required, the user must create a SequenceWrapper directly.

Parameters:

result - The final destination of the serialized output. Usually a StreamResult, but other kinds of Result are possible.

pipe - The PipelineConfiguration.

props - The serialization properties. If this includes the property SaxonOutputKeys.USE_CHARACTER_MAPS then the PipelineConfiguration must contain a non-null Controller, and the Executable associated with this Controller must have a CharacterMapIndex which is used to resolve the names of the character maps appearing in this property.

Returns:

the newly constructed Receiver that performs the required serialization

Throws:

XPathException - if any failure occurs

getReceiver

public Receiver getReceiver(Result result,
                            PipelineConfiguration pipe,

                            CharacterMapIndex charMapIndex)
                     throws XPathException

Get a Receiver that wraps a given Result object. Saxon calls this method to construct a serialization pipeline. The method can be overridden in a subclass; alternatively, the subclass can override the various methods used to instantiate components of the serialization pipeline.

Note that this method ignores the SaxonOutputKeys.WRAP output property. If wrapped output is required, the user must create a SequenceWrapper directly.

Parameters:

result - The final destination of the serialized output. Usually a StreamResult, but other kinds of Result are possible.

pipe - The PipelineConfiguration.

props - The serialization properties

charMapIndex - The index of character maps. Required if any of the serialization properties is SaxonOutputKeys.USE_CHARACTER_MAPS, in which case the named character maps listed in that property must be present in the index of character maps.

Returns:

the newly constructed Receiver that performs the required serialization

Throws:

XPathException
