Class AbstractMarshallerImpl

    java.lang.Object
      javax.xml.bind.helpers.AbstractMarshallerImpl

All Implemented Interfaces:
  Marshaller

    public abstract class AbstractMarshallerImpl

extends Object
implements Marshaller

Partial default `Marshaller` implementation.

This class provides a partial default implementation for the `Marshaller` interface.

The only methods that a JAXB Provider has to implement are `marshal(Object, javax.xml.transform.Result)`, `marshal(Object, javax.xml.stream.XMLStreamWriter)`, and `marshal(Object, javax.xml.stream.XMLEventWriter)`.

Since:
  JAXB1.0
See Also:
  `Marshaller`

  Specified by:
    `getProperty` in interface `Marshaller`
  Parameters:
    `name` - the name of the property to retrieve
  Returns:
    the value of the requested property

    `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:

### 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 default 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)`

### marshal

  Specified by:
    `marshal` in interface `Marshaller`
  Parameters:
    `obj` - The content tree rooted at jaxbElement to be marshalled.
    `writer` - XML will be sent to this writer.
  Throws:
    `JAXBException` - If any unexpected problem occurs during the marshalling.
    `MarshalException` - If the `ValidationEventHandler` returns false from its `handleEvent` method or the `Marshaller` is unable to marshal `obj` (or any object reachable from `obj`). See Marshalling a JAXB element.

### marshal

    public void marshal(Object obj,

  Description copied from interface: `Marshaller`
  Marshal the content tree rooted at `jaxbElement` into a `XMLStreamWriter`.

  Specified by:
    `marshal` in interface `Marshaller`
  Parameters:
    `obj` - The content tree to be marshalled.
    `writer` - XML will be sent to this writer.
  Throws:
    `JAXBException` - If any unexpected problem occurs during the marshalling.
    `MarshalException` - If the `ValidationEventHandler` returns false from its `handleEvent` method or the `Marshaller` is unable to marshal `obj` (or any object reachable from `obj`). See Marshalling a JAXB element.

### setSchema

    public void setSchema(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

### getSchema

    public Schema getSchema()

  Description copied from interface: `Marshaller`
  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.

  Specified by:
    `getSchema` in interface `Marshaller`
  Returns:
    the Schema object being used to perform marshal-time validation or null if not present.

### 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)`

### setAdapter

    public <A extends XmlAdapter> void setAdapter(Class<A> type,
                                                  A 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:
    `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.

### getAdapter

    public <A extends XmlAdapter> A getAdapter(Class<A> type)

  Description copied from interface: `Marshaller`
  Gets the adapter associated with the specified type. This is the reverse operation of the `Marshaller.setAdapter(javax.xml.bind.annotation.adapters.XmlAdapter)` method.

  Specified by:
    `getAdapter` in interface `Marshaller`

### setAttachmentMarshaller

    public void setAttachmentMarshaller(AttachmentMarshaller am)

  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`

### getAttachmentMarshaller

    public AttachmentMarshaller getAttachmentMarshaller()

  Specified by:
    `getAttachmentMarshaller` in interface `Marshaller`

### 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`

### getListener

    public Marshaller.Listener getListener()

  Description copied from interface: `Marshaller`

  Return `Marshaller.Listener` registered with this `Marshaller`.

  Specified by:
    `getListener` in interface `Marshaller`
