|
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} |
