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.

/**
 * Generates a wrapper element around XML representation.
 *
 * This is primarily intended to be used to produce a wrapper
 * XML element around collections. The annotation therefore supports
 * two forms of serialization shown below. 
 *
 * <pre>
 *    //Example: code fragment
 *      int[] names;
 *
 *    // XML Serialization Form 1 (Unwrapped collection)
 *    &lt;names&gt; ... &lt;/names&gt;
 *    &lt;names&gt; ... &lt;/names&gt;
 * 
 *    // XML Serialization Form 2 ( Wrapped collection )
 *    &lt;wrapperElement&gt;
 *       &lt;names&gt; value-of-item &lt;/names&gt;
 *       &lt;names&gt; value-of-item &lt;/names&gt;
 *       ....
 *    &lt;/wrapperElement&gt;
 * </pre>
 *
 * <p> The two serialized XML forms allow a null collection to be
 * represented either by absence or presence of an element with a
 * nillable attribute.
 * 
 * <p> <b>Usage</b> </p>
 * <p>
 * The <tt>@XmlElementWrapper</tt> annotation can be used with the
 * following program elements: 
 * <ul> 
 *   <li> JavaBean property </li>
 *   <li> non static, non transient field </li>
 * </ul>
 *
 * <p>The usage is subject to the following constraints:
 * <ul>
 *   <li> The property must be a collection property </li>
 *   <li> This annotation can be used with the following annotations:
 *            {@link XmlElement}, 
 *            {@link XmlElements},
 *            {@link XmlElementRef},
 *            {@link XmlElementRefs},
 *            {@link XmlJavaTypeAdapter}.</li>
 * </ul>
 *
 * <p>See "Package Specification" in javax.xml.bind.package javadoc for
 * additional common information.</p>
