setAdapter

public void setAdapter(java.lang.Class javaClass,
                       XmlAdapter adapter)

Description copied from interface: Marshaller

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.

Specified by:

setAdapter in interface Marshaller

Parameters:

javaClass - 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.

setAdapter

public void setAdapter(XmlAdapter adapter)

Description copied from interface: Marshaller

Associates a configured instance of XmlAdapter with this marshaller.

This is a convenience method that invokes setAdapter(adapter.getClass(),adapter);.

Specified by:

setAdapter in interface Marshaller

See Also:

Marshaller.setAdapter(Class,XmlAdapter)

setAttachmentMarshaller

public void setAttachmentMarshaller(AttachmentMarshaller attachmentMarshaller)

Description copied from interface: Marshaller

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.

Specified by:

setAttachmentMarshaller in interface Marshaller

setEventHandler

public void setEventHandler(ValidationEventHandler newValidationEventHandler)
                     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 default event handler.

Specified by:

setEventHandler in interface Marshaller

Parameters:

newValidationEventHandler - the validation event handler

Throws:

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

setListener

public void setListener(Marshaller.Listener listener)

Description copied from interface: Marshaller

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.

Specified by:

setListener in interface Marshaller

Parameters:

listener - an instance of a class that implements Marshaller.Listener

setMarshalCallbacks

public void setMarshalCallbacks(java.util.HashMap callbacks)

setProperty

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

Description copied from interface: Marshaller

Set the particular property in the underlying implementation of Marshaller. This method can only be used to set one of the standard JAXB defined properties above or a provider specific property. Attempting to set an undefined property will result in a PropertyException being thrown. See Supported Properties.

Specified by:

setProperty in interface Marshaller

Parameters:

key - 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

setSchema

public void setSchema(javax.xml.validation.Schema schema)

Description copied from interface: Marshaller

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.

Specified by:

setSchema in interface Marshaller

Parameters:

schema - Schema object to validate marshal operations against or null to disable validation

setQNameToGeneratedClasses

public void setQNameToGeneratedClasses(java.util.HashMap<javax.xml.namespace.QName,java.lang.Class> qNameToClass)
