All Implemented Interfaces:

Marshaller
```
public abstract class AbstractMarshallerImpl
extends java.lang.Object
implements Marshaller
```
Partial default Marshaller implementation.
This class provides a partial default implementation for the Marshaller interface.
The only methods that a Jakarta XML Binding 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:

1.6, JAXB 1.0

                     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 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.
    
    Specified by:
    
    setEventHandler in interface Marshaller
    
    Parameters:
    
    handler - the validation event handler
    
    Throws:

```
    Description copied from interface: Marshaller
    
    Specify the JAXP 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:

```
    Description copied from interface: Marshaller

    This is a convenience method that invokes setAdapter(adapter.getClass(),adapter);.
    
    Specified by:
    
    setAdapter in interface Marshaller
    
    Type Parameters:
    
    A - the type of the adapter

```
public <A extends XmlAdapter<?,?>> void setAdapter(java.lang.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.

    Type Parameters:
    
    A - the type of the adapter
    
    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(java.lang.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(A) method.
    
    Specified by:
    
    getAdapter in interface Marshaller
    
    Type Parameters:
    
    A - the type of the adapter
    
    Parameters:
    
    type - The type of the adapter. The specified instance will be used when XmlJavaTypeAdapter.value() refers to this type.
    
    Returns:
    
    The adapter associated with the specified type.

```
public void setAttachmentMarshaller(AttachmentMarshaller am)
```
    Description copied from interface: Marshaller
