|
34 * <p> |
|
35 * Prevents the mapping of a JavaBean property/type to XML representation. |
|
36 * <p> |
|
37 * The <tt>@XmlTransient</tt> annotation is useful for resolving name |
|
38 * collisions between a JavaBean property name and a field name or |
|
39 * preventing the mapping of a field/property. A name collision can |
|
40 * occur when the decapitalized JavaBean property name and a field |
|
41 * name are the same. If the JavaBean property refers to the field, |
|
42 * then the name collision can be resolved by preventing the |
|
43 * mapping of either the field or the JavaBean property using the |
|
44 * <tt>@XmlTransient</tt> annotation. |
|
45 * |
|
46 * <p> |
|
47 * When placed on a class, it indicates that the class shouldn't be mapped |
|
48 * to XML by itself. Properties on such class will be mapped to XML along |
|
49 * with its derived classes, as if the class is inlined. |
|
50 * |
|
51 * <p><b>Usage</b></p> |
|
52 * <p> The <tt>@XmlTransient</tt> annotation can be used with the following |
|
53 * program elements: |
|
54 * <ul> |
|
55 * <li> a JavaBean property </li> |
|
56 * <li> field </li> |
|
57 * <li> class </li> |
|
58 * </ul> |
|
59 * |
|
60 * <p><tt>@XmlTransient</tt>is mutually exclusive with all other |
|
61 * JAXB defined annotations. </p> |
|
62 * |
|
63 * <p>See "Package Specification" in javax.xml.bind.package javadoc for |
|
64 * additional common information.</p> |
|
65 * |
|
66 * <p><b>Example:</b> Resolve name collision between JavaBean property and |
|
67 * field name </p> |
|
68 * |
|
69 * <pre> |
|
70 * // Example: Code fragment |
|
71 * public class USAddress { |
|
72 * |
|
73 * // The field name "name" collides with the property name |
|
74 * // obtained by bean decapitalization of getName() below |
|
75 * @XmlTransient public String name; |
|
76 * |
|
77 * String getName() {..}; |
|
78 * String setName() {..}; |
|
79 * } |
|
80 * |
|
81 * |
|
82 * <!-- Example: XML Schema fragment --> |
|
83 * <xs:complexType name="USAddress"> |
|
84 * <xs:sequence> |
|
85 * <xs:element name="name" type="xs:string"/> |
