| * <b>Marshalling content tree rooted by a Jakarta XML Binding element</b><br> |
| * <blockquote> |
| * The first parameter of the overloaded |
| * {@code Marshaller.marshal(java.lang.Object, ...)} methods must be a |
| * Jakarta XML Binding element as computed by |
| * {@link JAXBIntrospector#isElement(java.lang.Object)}; |
| * otherwise, a {@code Marshaller.marshal} method must throw a |
| * {@link 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 {@link JAXBElement}, |
| * and pass the wrapper element as the first parameter to |
| * a {@code Marshaller.marshal} method. For java to schema binding, it |
| * is also possible to simply annotate the instance's class with |
| * @{@link XmlRootElement}. |
| * </blockquote> |
| * |
| * <p> |
| * <b>Encoding</b><br> |
| * <blockquote> |
| * By default, the Marshaller will use UTF-8 encoding when generating XML data |
| * to a {@code java.io.OutputStream}, or a {@code java.io.Writer}. Use the |
| * {@link #setProperty(String,Object) 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 |
| * <a href="http://www.w3.org/TR/2000/REC-xml-20001006#charencoding">W3C XML 1.0 |
| * Recommendation</a> and supported by your Java Platform. |
| * </blockquote> |
| * |
| * <p> |
| * <b>Validation and Well-Formedness</b><br> |
| * <blockquote> |
| * <p> |
| * 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 {@code 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. |
| * <p> |
| * 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, {@link jakarta.xml.bind.helpers.DefaultValidationEventHandler} is |
| * no longer used. |
| * |

| * <a id="supportedProps"></a> |
| * <b>Supported Properties</b><br> |
| * <blockquote> |
| * <p> |
| * All Jakarta XML Binding Providers are required to support the following set of properties. |
| * Some providers may support additional properties. |
| * <dl> |
| * <dt>{@code jaxb.encoding} - value must be a java.lang.String</dt> |
| * <dd>The output encoding to use when marshalling the XML data. The |
| * Marshaller will use "UTF-8" by default if this property is not |
| * specified.</dd> |
| * <dt>{@code jaxb.formatted.output} - value must be a java.lang.Boolean</dt> |
| * <dd>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.</dd> |
| * <dt>{@code jaxb.schemaLocation} - value must be a java.lang.String</dt> |
| * <dd>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 |
| * <a href="http://www.w3.org/TR/xmlschema-0/#schemaLocation">Section 5.6 |
| * of the W3C XML Schema Part 0: Primer</a> and specified in |
| * <a href="http://www.w3.org/TR/xmlschema-1/#Instance_Document_Constructions"> |
| * Section 2.6 of the W3C XML Schema Part 1: Structures</a>.</dd> |
| * <dt>{@code jaxb.noNamespaceSchemaLocation} - value must be a java.lang.String</dt> |
| * <dd>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 |
| * <a href="http://www.w3.org/TR/xmlschema-0/#schemaLocation">Section 5.6 |
| * of the W3C XML Schema Part 0: Primer</a> and specified in |
| * <a href="http://www.w3.org/TR/xmlschema-1/#Instance_Document_Constructions"> |
| * Section 2.6 of the W3C XML Schema Part 1: Structures</a>.</dd> |
| * <dt>{@code jaxb.fragment} - value must be a java.lang.Boolean</dt> |
| * <dd>This property determines whether or not document level events will be |
| * generated by the Marshaller. If the property is not specified, the |
| * default is {@code false}. This property has different implications depending |
| * on which marshal api you are using - when this property is set to true:<br> |
| * <ul> |
| * <li>{@link #marshal(Object,org.xml.sax.ContentHandler) marshal(Object,ContentHandler)} - the Marshaller won't |
| * invoke {@link org.xml.sax.ContentHandler#startDocument()} and |
| * {@link org.xml.sax.ContentHandler#endDocument()}.</li> |
| * <li>{@link #marshal(Object,org.w3c.dom.Node) marshal(Object,Node)} - the property has no effect on this |
| * API.</li> |
| * <li>{@link #marshal(Object,java.io.OutputStream) marshal(Object,OutputStream)} - the Marshaller won't |
| * generate an xml declaration.</li> |
| * <li>{@link #marshal(Object,java.io.Writer) marshal(Object,Writer)} - the Marshaller won't |
| * generate an xml declaration.</li> |
| * <li>{@link #marshal(Object,javax.xml.transform.Result) marshal(Object,Result)} - depends on the kind of |
| * Result object, see semantics for Node, ContentHandler, and Stream APIs</li> |
| * <li>{@link #marshal(Object,javax.xml.stream.XMLEventWriter) marshal(Object,XMLEventWriter)} - the |
| * Marshaller will not generate {@link javax.xml.stream.events.XMLEvent#START_DOCUMENT} and |
| * {@link javax.xml.stream.events.XMLEvent#END_DOCUMENT} events.</li> |
| * <li>{@link #marshal(Object,javax.xml.stream.XMLStreamWriter) marshal(Object,XMLStreamWriter)} - the |
| * Marshaller will not generate {@link javax.xml.stream.events.XMLEvent#START_DOCUMENT} and |
| * {@link javax.xml.stream.events.XMLEvent#END_DOCUMENT} events.</li> |
| * </ul> |
| * </dd> |
| * </dl> |
| * </blockquote> |
| * |
| * <p> |
| * <a id="marshalEventCallback"></a> |
| * <b>Marshal Event Callbacks</b><br> |
| * <blockquote> |
| * "The {@link 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. |
| * |
| * <p> |
| * 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: |
| * <blockquote> |
| * <pre> |
| * // 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); |
| * </pre> |
| * </blockquote> |
| * 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. |
| * <p> |
| * The external listener callback mechanism enables the registration of a {@link Listener} |
| * instance with a {@link Marshaller#setListener(Listener)}. The external listener receives all callback events, |
| * allowing for more centralized processing than per class defined callback methods. |
| * <p> |
| * 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 {@link Listener#beforeMarshal(Object)} and {@link Listener#afterMarshal(Object)}. |
| * <p> |
| * An event callback method throwing an exception terminates the current marshal process. |
