Constructor Detail

• W3CDomHandler

  public W3CDomHandler()

  Default constructor. It is up to a JAXB provider to decide which DOM implementation to use or how that is configured.

• W3CDomHandler

  public W3CDomHandler(javax.xml.parsers.DocumentBuilder builder)

  Constructor that allows applications to specify which DOM implementation to be used.

  Parameters:

  builder - must not be null. JAXB uses this DocumentBuilder to create a new element.

Method Detail

• getBuilder

  public javax.xml.parsers.DocumentBuilder getBuilder()

• setBuilder

  public void setBuilder(javax.xml.parsers.DocumentBuilder builder)

• createUnmarshaller

  public javax.xml.transform.dom.DOMResult createUnmarshaller(ValidationEventHandler errorHandler)

  Description copied from interface: DomHandler
  When a JAXB provider needs to unmarshal a part of a document into an infoset representation, it first calls this method to create a Result object.

  A JAXB provider will then send a portion of the XML into the given result. Such a portion always form a subtree of the whole XML document rooted at an element.

  Specified by:

  createUnmarshaller in interface DomHandler<org.w3c.dom.Element,javax.xml.transform.dom.DOMResult>

  Parameters:

  errorHandler - if any error happens between the invocation of this method and the invocation of DomHandler.getElement(Result), they must be reported to this handler. The caller must provide a non-null error handler. The Result object created from this method may hold a reference to this error handler.

  Returns:

  null if the operation fails. The error must have been reported to the error handler.

• getElement

  public org.w3c.dom.Element getElement(javax.xml.transform.dom.DOMResult r)

  Description copied from interface: DomHandler
  Once the portion is sent to the Result. This method is called by a JAXB provider to obtain the unmarshalled element representation.

  Multiple invocations of this method may return different objects. This method can be invoked only when the whole sub-tree are fed to the Result object.

  Specified by:

  getElement in interface DomHandler<org.w3c.dom.Element,javax.xml.transform.dom.DOMResult>

  Parameters:

  r - The Result object created by DomHandler.createUnmarshaller(ValidationEventHandler).

  Returns:

  null if the operation fails. The error must have been reported to the error handler.

• marshal

  public javax.xml.transform.Source marshal(org.w3c.dom.Element element,
                                   ValidationEventHandler errorHandler)

  Description copied from interface: DomHandler
  This method is called when a JAXB provider needs to marshal an element to XML.

  If non-null, the returned Source must contain a whole document rooted at one element, which will then be weaved into a bigger document that the JAXB provider is marshalling.

  Specified by:

  marshal in interface DomHandler<org.w3c.dom.Element,javax.xml.transform.dom.DOMResult>

  errorHandler - Receives any errors happened during the process of converting an element into a Source. The caller must provide a non-null error handler.

  Returns:

  null if there was an error. The error should have been reported to the handler.
