## net.sf.saxon.s9api
Class Serializer

    java.lang.Object
      net.sf.saxon.s9api.Serializer

All Implemented Interfaces:
  Destination

    public class Serializer

extends java.lang.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 `Serializable` interface.

The serialization may be influenced by a number of serialization parameters. A parameter has a name, which is an instance of `Serializer.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_".

Method Detail

### setOutputProperty

    public void setOutputProperty(Serializer.Property property,
                                  java.lang.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:
    `java.lang.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.

### getOutputProperty

    public java.lang.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.

### setOutputWriter

    public void setOutputWriter(java.io.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.

### setOutputStream

    public void setOutputStream(java.io.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.

### setOutputFile

    public void setOutputFile(java.io.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.

### getOutputDestination

    public java.lang.Object getOutputDestination()

  Get the current output destination.

  Returns:
    an OutputStream, Writer, or File, depending on the previous calls to `setOutputStream(java.io.OutputStream)`, `setOutputWriter(java.io.Writer)`, or `setOutputFile(java.io.File)`

### getReceiver

    public Receiver getReceiver(Configuration config)
                         throws SaxonApiException

  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.

  Specified by:
    `getReceiver` in interface `Destination`
  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
  Throws:
    `SaxonApiException` - if the Receiver cannot be created
