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 * &#64;XmlTransient public String name;
76 *
77 * String getName() {..};
78 * String setName() {..};
79 * }
80 *
81 *
82 * &lt;!-- Example: XML Schema fragment -->
83 * &lt;xs:complexType name="USAddress">
84 * &lt;xs:sequence>
85 * &lt;xs:element name="name" type="xs:string"/>
86 * &lt;/xs:sequence>
87 * &lt;/xs:complexType>
