|
36 * Used to map a property to a list simple type. |
|
37 * |
|
38 * <p><b>Usage</b> </p> |
|
39 * <p> |
|
40 * The <tt>@XmlList</tt> annotation can be used with the |
|
41 * following program elements: |
|
42 * <ul> |
|
43 * <li> JavaBean property </li> |
|
44 * <li> field </li> |
|
45 * </ul> |
|
46 * |
|
47 * <p> |
|
48 * When a collection property is annotated just with @XmlElement, |
|
49 * each item in the collection will be wrapped by an element. |
|
50 * For example, |
|
51 * |
|
52 * <pre> |
|
53 * @XmlRootElement |
|
54 * class Foo { |
|
55 * @XmlElement |
|
56 * List<String> data; |
|
57 * } |
|
58 * </pre> |
|
59 * |
|
60 * would produce XML like this: |
|
61 * |
|
62 * <pre> |
|
63 * <foo> |
|
64 * <data>abc</data> |
|
65 * <data>def</data> |
|
66 * </foo> |
|
67 * </pre> |
|
68 * |
|
69 * @XmlList annotation, on the other hand, allows multiple values to be |
|
70 * represented as whitespace-separated tokens in a single element. For example, |
|
71 * |
|
72 * <pre> |
|
73 * @XmlRootElement |
|
74 * class Foo { |
|
75 * @XmlElement |
|
76 * @XmlList |
|
77 * List<String> data; |
|
78 * } |
|
79 * </pre> |
|
80 * |
|
81 * the above code will produce XML like this: |
|
82 * |
|
83 * <pre> |
|
84 * <foo> |
|
85 * <data>abc def</data> |
|
86 * </foo> |
|
87 * </pre> |
|
88 * |
|
89 * <p>This annotation can be used with the following annotations: |
|
90 * {@link XmlElement}, |
|
91 * {@link XmlAttribute}, |
|
92 * {@link XmlValue}, |
|
93 * {@link XmlIDREF}. |
|
94 * <ul> |
|
95 * <li> The use of <tt>@XmlList</tt> with {@link XmlValue} while |
|
96 * allowed, is redundant since {@link XmlList} maps a |
|
97 * collection type to a simple schema type that derives by |
|
98 * list just as {@link XmlValue} would. </li> |
|
99 * |
|
100 * <li> The use of <tt>@XmlList</tt> with {@link XmlAttribute} while |
|
101 * allowed, is redundant since {@link XmlList} maps a |
|
102 * collection type to a simple schema type that derives by |
|
103 * list just as {@link XmlAttribute} would. </li> |
|
104 * </ul> |
