All Implemented Interfaces:
Serializable

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.

    • 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
      Returns:
      the newly constructed Receiver that performs the required serialization
      Throws:
      XPathException
