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

    • 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:

    • marshal

      public void marshal(Object obj, XMLEventWriter writer) throws JAXBException

      marshal in interface Marshaller
      Parameters:
      obj - The content tree to be marshalled.
      writer - XML will be sent to this writer.
      Throws:

    • 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:

    • 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

      setListener in interface Marshaller
      Parameters:
      listener - an instance of a class that implements Marshaller.Listener

    • getListener
