| /** |
| * INTERNAL: |
| * <p><b>Purpose:</b>Provide an implementation of the TopLink OX XMLAttachmentUnmarshaller |
| * interface that wraps an implementation of the JAXB AttachmentUnmarshaller interface. |
| * <p><b>Responsibilities:</b><ul> |
| * <li>Implement the XMLAttachmentUnmarshaller interface</li> |
| * <li>Adapt events from the TopLink OX Attachment API to the JAXB 2.0 Attachment API</li> |
| * </ul> |
| * <p>This class allows TopLink OXM to do attachment unmarshalling callback events to a JAXB |
| * 2.0 Listener without adding a dependancy on JAXB 2.0 into core TopLink. The Adapter class |
| * wraps a javax.xml.bin.attachment.AttachmentUnmarshaller and passes on the events as they're raised |
| * |
| * @see jakarta.xml.bind.attachment.AttachmentUnmarshaller |
| * @see org.eclipse.persistence.oxm.attachment.XMLAttachmentUnmarshaller |
| * @since Oracle TopLink 11.1.1.0.0 |
