JAXB API 2.2.12 Source Code

Java Architecture for XML Binding (JAXB) is a Java API that allows Java developers to map Java classes to XML representations.

jaxb-api-2.2.12.jar is the JAR file for the JAXB API 2.2 specification. You can download and use it directly without any building process as shown in the last tutorial.

If you want to rebuild the JAR file, you can download the source code at JAXB API Maven Website.

/**
 * Enable synchronization between XML infoset nodes and JAXB objects 
 * representing same XML document.
 *
 * <p>
 * An instance of this class maintains the association between XML nodes of
 * an infoset preserving view and a JAXB representation of an XML document. 
 * Navigation between the two views is provided by the methods
 * {@link #getXMLNode(Object)} and {@link #getJAXBNode(Object)}.
 * 
 * <p>
 * Modifications can be made to either the infoset preserving view or the 
 * JAXB representation of the document while the other view remains 
 * unmodified. The binder is able to synchronize the changes made in the 
 * modified view back into the other view using the appropriate
 * Binder update methods, {@link #updateXML(Object, Object)} or 
 * {@link #updateJAXB(Object)}.
 * 
 * <p>
 * A typical usage scenario is the following:
 * <ul>
 *   <li>load XML document into an XML infoset representation</li>
 *   <li>{@link #unmarshal(Object)} XML infoset view to JAXB view.
 *       (Note to conserve resources, it is possible to only unmarshal a
 *       subtree of the XML infoset view to the JAXB view.)</li>
 *   <li>application access/updates JAXB view of XML document.</li>
 *   <li>{@link #updateXML(Object)} synchronizes modifications to JAXB view 
 *       back into the XML infoset view. Update operation preserves as 
 *       much of original XML infoset as possible (i.e. comments, PI, ...)</li>
 * </ul>
 * 
 * <p>
 * A Binder instance is created using the factory method 
 * {@link JAXBContext#createBinder()} or {@link JAXBContext#createBinder(Class)}.
 *
 * <p>
 * The template parameter, <code>XmlNode</code>, is the
 * root interface/class for the XML infoset preserving representation.
 * A Binder implementation is required to minimally support
 * an <code>XmlNode</code> value of <code>org.w3c.dom.Node.class</code>. 
 * A Binder implementation can support alternative XML infoset 
 * preserving representations.
