Marshaller

All Known Implementing Classes:

AbstractMarshallerImpl
```
public interface Marshaller
```
The Marshaller class is responsible for governing the process of serializing Java content trees back into XML data. It provides the basic marshalling methods:
Assume the following setup code for all following code fragments:
```
       JAXBContext jc = JAXBContext.newInstance( "com.acme.foo" );
       Unmarshaller u = jc.createUnmarshaller();
       Object element = u.unmarshal( new File( "foo.xml" ) );
       Marshaller m = jc.createMarshaller();
    
```
Marshalling to a File:
```
       OutputStream os = new FileOutputStream( "nosferatu.xml" );
       m.marshal( element, os );
    
```
Marshalling to a SAX ContentHandler:
```
       // assume MyContentHandler instanceof ContentHandler
       m.marshal( element, new MyContentHandler() );  
    
```
Marshalling to a DOM Node:
```
       DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
       dbf.setNamespaceAware(true);
       DocumentBuilder db = dbf.newDocumentBuilder();
       Document doc = db.newDocument();

       m.marshal( element, doc );
    
```
Marshalling to a java.io.OutputStream:
```
       m.marshal( element, System.out );
    
```
Marshalling to a java.io.Writer:
```
       m.marshal( element, new PrintWriter( System.out ) );
    
```
Marshalling to a javax.xml.transform.SAXResult:
```
       // assume MyContentHandler instanceof ContentHandler
       SAXResult result = new SAXResult( new MyContentHandler() );

       m.marshal( element, result );
    
```
Marshalling to a javax.xml.transform.DOMResult:
```
       DOMResult result = new DOMResult();
       
       m.marshal( element, result );
    
```
Marshalling to a javax.xml.transform.StreamResult:
```
       StreamResult result = new StreamResult( System.out );
 
       m.marshal( element, result );
    
```
Marshalling to a javax.xml.stream.XMLStreamWriter:
```
       XMLStreamWriter xmlStreamWriter = 
           XMLOutputFactory.newInstance().createXMLStreamWriter( ... );
 
       m.marshal( element, xmlStreamWriter );
    
```
Marshalling to a javax.xml.stream.XMLEventWriter:
```
       XMLEventWriter xmlEventWriter = 
           XMLOutputFactory.newInstance().createXMLEventWriter( ... );
 
       m.marshal( element, xmlEventWriter );
    
```
Marshalling content tree rooted by a Jakarta XML Binding element

The first parameter of the overloaded Marshaller.marshal(java.lang.Object, ...) methods must be a Jakarta XML Binding element as computed by JAXBIntrospector.isElement(java.lang.Object); otherwise, a Marshaller.marshal method must throw a MarshalException. There exist two mechanisms to enable marshalling an instance that is not a Jakarta XML Binding element. One method is to wrap the instance as a value of a JAXBElement, and pass the wrapper element as the first parameter to a Marshaller.marshal method. For java to schema binding, it is also possible to simply annotate the instance's class with @XmlRootElement.

Encoding

By default, the Marshaller will use UTF-8 encoding when generating XML data to a java.io.OutputStream, or a java.io.Writer. Use the setProperty API to change the output encoding used during these marshal operations. Client applications are expected to supply a valid character encoding name as defined in the W3C XML 1.0 Recommendation and supported by your Java Platform.

Validation and Well-Formedness

Client applications are not required to validate the Java content tree prior to calling any of the marshal API's. Furthermore, there is no requirement that the Java content tree be valid with respect to its original schema in order to marshal it back into XML data. Different Jakarta XML Binding Providers will support marshalling invalid Java content trees at varying levels, however all Jakarta XML Binding Providers must be able to marshal a valid content tree back to XML data. A Jakarta XML Binding Provider must throw a MarshalException when it is unable to complete the marshal operation due to invalid content. Some Jakarta XML Binding Providers will fully allow marshalling invalid content, others will fail on the first validation error.
Even when schema validation is not explictly enabled for the marshal operation, it is possible that certain types of validation events will be detected during the operation. Validation events will be reported to the registered event handler. If the client application has not registered an event handler prior to invoking one of the marshal API's, then events will be delivered to a default event handler which will terminate the marshal operation after encountering the first error or fatal error. Note that for Jakarta XML Binding and later versions, DefaultValidationEventHandler is no longer used.

Supported Properties
All Jakarta XML Binding Providers are required to support the following set of properties. Some providers may support additional properties.
jaxb.encoding - value must be a java.lang.String

The output encoding to use when marshalling the XML data. The Marshaller will use "UTF-8" by default if this property is not specified.

jaxb.formatted.output - value must be a java.lang.Boolean

This property controls whether or not the Marshaller will format the resulting XML data with line breaks and indentation. A true value for this property indicates human readable indented xml data, while a false value indicates unformatted xml data. The Marshaller will default to false (unformatted) if this property is not specified.

jaxb.schemaLocation - value must be a java.lang.String

This property allows the client application to specify an xsi:schemaLocation attribute in the generated XML data. The format of the schemaLocation attribute value is discussed in an easy to understand, non-normative form in Section 5.6 of the W3C XML Schema Part 0: Primer and specified in Section 2.6 of the W3C XML Schema Part 1: Structures.

jaxb.noNamespaceSchemaLocation - value must be a java.lang.String

This property allows the client application to specify an xsi:noNamespaceSchemaLocation attribute in the generated XML data. The format of the schemaLocation attribute value is discussed in an easy to understand, non-normative form in Section 5.6 of the W3C XML Schema Part 0: Primer and specified in Section 2.6 of the W3C XML Schema Part 1: Structures.

jaxb.fragment - value must be a java.lang.Boolean
This property determines whether or not document level events will be generated by the Marshaller. If the property is not specified, the default is false. This property has different implications depending on which marshal api you are using - when this property is set to true:

marshal(Object,ContentHandler) - the Marshaller won't invoke ContentHandler.startDocument() and ContentHandler.endDocument().

marshal(Object,Node) - the property has no effect on this API.

marshal(Object,OutputStream) - the Marshaller won't generate an xml declaration.

marshal(Object,Writer) - the Marshaller won't generate an xml declaration.

marshal(Object,Result) - depends on the kind of Result object, see semantics for Node, ContentHandler, and Stream APIs

marshal(Object,XMLEventWriter) - the Marshaller will not generate XMLStreamConstants.START_DOCUMENT and XMLStreamConstants.END_DOCUMENT events.

marshal(Object,XMLStreamWriter) - the Marshaller will not generate XMLStreamConstants.START_DOCUMENT and XMLStreamConstants.END_DOCUMENT events.
Marshal Event Callbacks
"The Marshaller provides two styles of callback mechanisms that allow application specific processing during key points in the unmarshalling process. In 'class defined' event callbacks, application specific code placed in Jakarta XML Binding mapped classes is triggered during marshalling. 'External listeners' allow for centralized processing of marshal events in one callback method rather than by type event callbacks.
Class defined event callback methods allow any Jakarta XML Binding mapped class to specify its own specific callback methods by defining methods with the following method signatures:
```
   // Invoked by Marshaller after it has created an instance of this object.
   boolean beforeMarshal(Marshaller);
 
   // Invoked by Marshaller after it has marshalled all properties of this object.
   void afterMarshal(Marshaller);
 
```
The class defined event callback methods should be used when the callback method requires access to non-public methods and/or fields of the class.
The external listener callback mechanism enables the registration of a Marshaller.Listener instance with a setListener(Listener). The external listener receives all callback events, allowing for more centralized processing than per class defined callback methods.
The 'class defined' and external listener event callback methods are independent of each other, both can be called for one event. The invocation ordering when both listener callback methods exist is defined in Marshaller.Listener.beforeMarshal(Object) and Marshaller.Listener.afterMarshal(Object).
An event callback method throwing an exception terminates the current marshal process.

  - setEventHandler
```
void setEventHandler(ValidationEventHandler handler)
              throws JAXBException
```
    Allow an application to register a validation event handler.
    The validation event handler will be called by the Jakarta XML Binding Provider if any validation errors are encountered during calls to any of the marshal API's. If the client application does not register a validation event handler before invoking one of the marshal methods, then validation events will be handled by the default event handler which will terminate the marshal operation after the first error or fatal error is encountered.
    Calling this method with a null parameter will cause the Marshaller to revert back to the default default event handler.
    
    Parameters:
    
    handler - the validation event handler
    
    Throws:
    
    JAXBException - if an error was encountered while setting the event handler
  - getEventHandler
```
ValidationEventHandler getEventHandler()
                                throws JAXBException
```
    Return the current event handler or the default event handler if one hasn't been set.
    
    Returns:
    
    the current ValidationEventHandler or the default event handler if it hasn't been set
    
    Throws:
    
    JAXBException - if an error was encountered while getting the current event handler
  - setAdapter
```
void setAdapter(XmlAdapter adapter)
```
    Associates a configured instance of XmlAdapter with this marshaller.
    This is a convenience method that invokes setAdapter(adapter.getClass(),adapter);.
    
    Throws:
    
    java.lang.IllegalArgumentException - if the adapter parameter is null.
    
    java.lang.UnsupportedOperationException - if invoked agains a JAXB 1.0 implementation.

                                       A adapter)
```
    Associates a configured instance of XmlAdapter with this marshaller.
    Every marshaller internally maintains a Map<Class,XmlAdapter>, which it uses for marshalling classes whose fields/methods are annotated with XmlJavaTypeAdapter.
    This method allows applications to use a configured instance of XmlAdapter. When an instance of an adapter is not given, a marshaller will create one by invoking its default constructor.
    
    Parameters:
    
    type - The type of the adapter. The specified instance will be used when XmlJavaTypeAdapter.value() refers to this type.
    
    adapter - The instance of the adapter to be used. If null, it will un-register the current adapter set for this type.
    
    Throws:
    
    java.lang.IllegalArgumentException - if the type parameter is null.
    
    java.lang.UnsupportedOperationException - if invoked agains a JAXB 1.0 implementation.

    Gets the adapter associated with the specified type. This is the reverse operation of the setAdapter(jakarta.xml.bind.annotation.adapters.XmlAdapter) method.
    
    Throws:
    
    java.lang.IllegalArgumentException - if the type parameter is null.
    
    java.lang.UnsupportedOperationException - if invoked agains a JAXB 1.0 implementation.

  - setAttachmentMarshaller
```
void setAttachmentMarshaller(AttachmentMarshaller am)
```
    Associate a context that enables binary data within an XML document to be transmitted as XML-binary optimized attachment. The attachment is referenced from the XML document content model by content-id URIs(cid) references stored within the xml document.
    
    Throws:
    
    java.lang.IllegalStateException - if attempt to concurrently call this method during a marshal operation.
  - getAttachmentMarshaller
```
AttachmentMarshaller getAttachmentMarshaller()
```
  - setSchema
```
void setSchema(javax.xml.validation.Schema schema)
```
    Specify the JAXP 1.3 Schema object that should be used to validate subsequent marshal operations against. Passing null into this method will disable validation.
    This method allows the caller to validate the marshalled XML as it's marshalled.
    Initially this property is set to null.
    
    Parameters:
    
    schema - Schema object to validate marshal operations against or null to disable validation
    
    Throws:
    
    java.lang.UnsupportedOperationException - could be thrown if this method is invoked on an Marshaller created from a JAXBContext referencing JAXB 1.0 mapped classes
    
    Since:
    
    1.6, JAXB 2.0
  - getSchema
```
javax.xml.validation.Schema getSchema()
```
    Get the JAXP 1.3 Schema object being used to perform marshal-time validation. If there is no Schema set on the marshaller, then this method will return null indicating that marshal-time validation will not be performed.
    
    Returns:
    
    the Schema object being used to perform marshal-time validation or null if not present.
    
    Throws:
    
    java.lang.UnsupportedOperationException - could be thrown if this method is invoked on an Marshaller created from a JAXBContext referencing JAXB 1.0 mapped classes

  - setListener
```
void setListener(Marshaller.Listener listener)
```
    Register marshal event callback Marshaller.Listener with this Marshaller.
    There is only one Listener per Marshaller. Setting a Listener replaces the previous set Listener. One can unregister current Listener by setting listener to null.
    
    Parameters:
    
    listener - an instance of a class that implements Marshaller.Listener
    
    Since:
    
    1.6, JAXB 2.0
  - getListener
```
Marshaller.Listener getListener()
```
    Return Marshaller.Listener registered with this Marshaller.
    
    Returns:
    
    registered Marshaller.Listener or null if no Listener is registered with this Marshaller.
