49 * Use an adapter that implements {@link XmlAdapter} for custom marshaling.
50 *
51 * <p> <b> Usage: </b> </p>
52 *
53 * <p> The <tt>@XmlJavaTypeAdapter</tt> annotation can be used with the
54 * following program elements:
55 * <ul>
56 * <li> a JavaBean property </li>
57 * <li> field </li>
58 * <li> parameter </li>
59 * <li> package </li>
60 * <li> from within {@link XmlJavaTypeAdapters} </li>
61 * </ul>
62 *
63 * <p> When <tt>@XmlJavaTypeAdapter</tt> annotation is defined on a
64 * class, it applies to all references to the class.
65 * <p> When <tt>@XmlJavaTypeAdapter</tt> annotation is defined at the
66 * package level it applies to all references from within the package
67 * to <tt>@XmlJavaTypeAdapter.type()</tt>.
68 * <p> When <tt>@XmlJavaTypeAdapter</tt> annotation is defined on the
69 * field, property or parameter, then the annotation applies to the
70 * field, property or the parameter only.
71 * <p> A <tt>@XmlJavaTypeAdapter</tt> annotation on a field, property
72 * or parameter overrides the <tt>@XmlJavaTypeAdapter</tt> annotation
73 * associated with the class being referenced by the field, property
74 * or parameter.
75 * <p> A <tt>@XmlJavaTypeAdapter</tt> annotation on a class overrides
76 * the <tt>@XmlJavaTypeAdapter</tt> annotation specified at the
77 * package level for that class.
78 *
79 * <p>This annotation can be used with the following other annotations:
80 * {@link XmlElement}, {@link XmlAttribute}, {@link XmlElementRef},
81 * {@link XmlElementRefs}, {@link XmlAnyElement}. This can also be
82 * used at the package level with the following annotations:
83 * {@link XmlAccessorType}, {@link XmlSchema}, {@link XmlSchemaType},
84 * {@link XmlSchemaTypes}.
85 *
86 * <p><b> Example: </b> See example in {@link XmlAdapter}
87 *
