+/**
+ * Adapts a Java type for custom marshaling.
+ *
+ * <p> <b> Usage: </b> </p>
+ *
+ * <p>
+ * Some Java types do not map naturally to a XML representation, for
+ * example <tt>HashMap</tt> or other non JavaBean classes. Conversely,
+ * a XML repsentation may map to a Java type but an application may
+ * choose to accesss the XML representation using another Java
+ * type. For example, the schema to Java binding rules bind
+ * xs:DateTime by default to XmlGregorianCalendar. But an application
+ * may desire to bind xs:DateTime to a custom type,
+ * MyXmlGregorianCalendar, for example. In both cases, there is a
+ * mismatch between <i> bound type </i>, used by an application to
+ * access XML content and the <i> value type</i>, that is mapped to an
+ * XML representation.
+ *
+ * <p>
+ * This abstract class defines methods for adapting a bound type to a value
+ * type or vice versa. The methods are invoked by the JAXB binding
+ * framework during marshaling and unmarshalling:
+ *
+ * <ul>
+ *   <li> <b> XmlAdapter.marshal(...): </b> During marshalling, JAXB
+ *        binding framework invokes XmlAdapter.marshal(..) to adapt a
+ *        bound type to value type, which is then marshaled to XML
+ *        representation. </li>
+ *
+ *   <li> <b> XmlAdapter.unmarshal(...): </b> During unmarshalling,
+ *        JAXB binding framework first unmarshals XML representation
+ *        to a value type and then invokes XmlAdapter.unmarshal(..) to
+ *        adapt the value type to a bound type. </li>
+ * </ul>
+ *
+ * Writing an adapter therefore involves the following steps:
+ *
+ * <ul>
+ *   <li> Write an adapter that implements this abstract class. </li>
+ *   <li> Install the adapter using the annotation {@link
+ *        XmlJavaTypeAdapter} </li>
+ * </ul>
+ *
+ * <p><b>Example:</b> Customized mapping of <tt>HashMap</tt></p>
+ * <p> The following example illustrates the use of
+ * <tt>&#64;XmlAdapter</tt> and <tt>&#64;XmlJavaTypeAdapter</tt> to
+ * customize the mapping of a <tt>HashMap</tt>.
+ *
+ * <p> <b> Step 1: </b> Determine the desired XML representation for HashMap.
+ *
+ * <pre>
+ *     &lt;hashmap>
+ *         &lt;entry key="id123">this is a value&lt;/entry>
+ *         &lt;entry key="id312">this is another value&lt;/entry>
+ *         ...
+ *       &lt;/hashmap>
+ * </pre>
+ *
+ * <p> <b> Step 2: </b> Determine the schema definition that the
+ * desired XML representation shown above should follow.
+ *
+ * <pre>
+ *
+ *     &lt;xs:complexType name="myHashMapType">
+ *       &lt;xs:sequence>
+ *         &lt;xs:element name="entry" type="myHashMapEntryType"
+ *                        minOccurs = "0" maxOccurs="unbounded"/>
+ *       &lt;/xs:sequence>
+ *     &lt;/xs:complexType>
+ *
+ *     &lt;xs:complexType name="myHashMapEntryType">
+ *       &lt;xs:simpleContent>
+ *         &lt;xs:extension base="xs:string">
+ *           &lt;xs:attribute name="key" type="xs:int"/>
+ *         &lt;/xs:extension>
+ *       &lt;/xs:simpleContent>
+ *     &lt;/xs:complexType>
+ *
+ * </pre>
+ *
+ * <p> <b> Step 3: </b> Write value types that can generate the above
+ * schema definition.
+ *
+ * <pre>
+ *     public class MyHashMapType {
+ *         List&lt;MyHashMapEntryType> entry;
+ *     }
+ *
+ *     public class MyHashMapEntryType {
+ *         &#64;XmlAttribute
+ *         public Integer key;
+ *
+ *         &#64;XmlValue
+ *         public String value;
+ *     }
+ * </pre>
+ *
+ * <p> <b> Step 4: </b> Write the adapter that adapts the value type,
+ * MyHashMapType to a bound type, HashMap, used by the application.
+ *
+ * <pre>
+ *     public final class MyHashMapAdapter extends
+ *                        XmlAdapter&lt;MyHashMapType,HashMap> { ... }
+ *
+ * </pre>
+ *
+ * <p> <b> Step 5: </b> Use the adapter.
+ *
+ * <pre>
+ *     public class Foo {
+ *         &#64;XmlJavaTypeAdapter(MyHashMapAdapter.class)
+ *         HashMap hashmap;
+ *         ...
+ *     }
+ * </pre>
+ *
+ * The above code fragment will map to the following schema:
+ *
+ * <pre>
+ *     &lt;xs:complexType name="Foo">
+ *       &lt;xs:sequence>
+ *         &lt;xs:element name="hashmap" type="myHashMapType"
+ *       &lt;/xs:sequence>
+ *     &lt;/xs:complexType>
+ * </pre>
+ *
+ * @param <BoundType>
+ *      The type that JAXB doesn't know how to handle. An adapter is written
+ *      to allow this type to be used as an in-memory representation through
+ *      the <tt>ValueType</tt>.
+ * @param <ValueType>
+ *      The type that JAXB knows how to handle out of the box.
