marshal

public final void marshal(java.lang.Object obj,
                          ContentHandler handler)
                   throws JAXBException

Description copied from interface: Marshaller

Marshal the content tree rooted at obj into SAX2 events.

Specified by:

marshal in interface Marshaller

Parameters:

obj - The content tree to be marshalled.

handler - XML will be sent to this handler as SAX2 events.

Throws:

JAXBException - If any unexpected problem occurs during the marshalling.

marshal

public final void marshal(java.lang.Object obj,
                          Node node)
                   throws JAXBException

Description copied from interface: Marshaller

Marshal the content tree rooted at obj into a DOM tree.

Specified by:

marshal in interface Marshaller

Parameters:

obj - The content tree to be marshalled.

node - DOM nodes will be added as children of this node. This parameter must be a Node that accepts children (Document, DocumentFragment, or Element)

Throws:

JAXBException - If any unexpected problem occurs during the marshalling.

getNode

public Node getNode(java.lang.Object obj)
             throws JAXBException

By default, the getNode method is unsupported and throw an UnsupportedOperationException. Implementations that choose to support this method must override this method.

Specified by:

getNode in interface Marshaller

Parameters:

obj - - JAXB Java representation of XML content

Returns:

the DOM tree view of the contentTree

Throws:

JAXBException - If any unexpected problem occurs

getEncoding

protected java.lang.String getEncoding()

Convenience method for getting the current output encoding.

Returns:

the current encoding or "UTF-8" if it hasn't been set.

setEncoding

protected void setEncoding(java.lang.String encoding)

Convenience method for setting the output encoding.

Parameters:

encoding - a valid encoding as specified in the Marshaller class documentation

getSchemaLocation

protected java.lang.String getSchemaLocation()

Convenience method for getting the current schemaLocation.

Returns:

the current schemaLocation or null if it hasn't been set

setSchemaLocation

protected void setSchemaLocation(java.lang.String location)

Convenience method for setting the schemaLocation.

Parameters:

location - the schemaLocation value

getNoNSSchemaLocation

protected java.lang.String getNoNSSchemaLocation()

Convenience method for getting the current noNamespaceSchemaLocation.

Returns:

the current noNamespaceSchemaLocation or null if it hasn't been set

setNoNSSchemaLocation

protected void setNoNSSchemaLocation(java.lang.String location)

Convenience method for setting the noNamespaceSchemaLocation.

Parameters:

getJavaEncoding

protected java.lang.String getJavaEncoding(java.lang.String encoding)
                                    throws java.io.UnsupportedEncodingException

Gets the corresponding Java encoding name from an IANA name. This method is a helper method for the derived class to convert encoding names.

Throws:

java.io.UnsupportedEncodingException - If this implementation couldn't find the Java encoding name.

setProperty

public void setProperty(java.lang.String name,
                        java.lang.Object value)
                 throws PropertyException

Default implementation of the setProperty method handles the four defined properties in Marshaller. If a provider needs to handle additional properties, it should override this method in a derived class.

Specified by:

setProperty in interface Marshaller

Parameters:

name - the name of the property to be set. This value can either be specified using one of the constant fields or a user supplied string.

value - the value of the property to be set

Throws:

PropertyException - when there is an error processing the given property or value

getProperty

public java.lang.Object getProperty(java.lang.String name)
                             throws PropertyException

Default implementation of the getProperty method handles the four defined properties in Marshaller. If a provider needs to support additional provider specific properties, it should override this method in a derived class.

Specified by:

getProperty in interface Marshaller

Parameters:

name - the name of the property to retrieve

Returns:

the value of the requested property

Throws:

PropertyException - when there is an error retrieving the given property or value property name

getEventHandler

public ValidationEventHandler getEventHandler()
                                       throws JAXBException

Description copied from interface: Marshaller

Return the current event handler or the default event handler if one hasn't been set.

Specified by:

getEventHandler in interface Marshaller

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

See Also:

Marshaller.getEventHandler()

setEventHandler

public void setEventHandler(ValidationEventHandler handler)
                     throws JAXBException

Description copied from interface: Marshaller

Allow an application to register a validation event handler.

The validation event handler will be called by the JAXB 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 vefault event handler.

Specified by:

setEventHandler in interface Marshaller

Parameters:

handler - the validation event handler

Throws:

JAXBException - if an error was encountered while setting the event handler

See Also:

Marshaller.setEventHandler(ValidationEventHandler)
