ohair@286 | 44 | * <p> |
ohair@286 | 45 | * This annotation serves as a "catch-all" property while unmarshalling |
ohair@286 | 46 | * xml content into a instance of a JAXB annotated class. It typically |
ohair@286 | 47 | * annotates a multi-valued JavaBean property, but it can occur on |
ohair@286 | 48 | * single value JavaBean property. During unmarshalling, each xml element |
ohair@286 | 49 | * that does not match a static @XmlElement or @XmlElementRef |
ohair@286 | 50 | * annotation for the other JavaBean properties on the class, is added to this |
ohair@286 | 51 | * "catch-all" property. |

ohair@286 | 70 | * <h2>Restriction usage constraints</h2> |
ohair@286 | 71 | * <p> |
ohair@286 | 72 | * This annotation is mutually exclusive with |
ohair@286 | 73 | * {@link XmlElement}, {@link XmlAttribute}, {@link XmlValue}, |
ohair@286 | 74 | * {@link XmlElements}, {@link XmlID}, and {@link XmlIDREF}. |
ohair@286 | 75 | * |
ohair@286 | 76 | * <p> |
ohair@286 | 77 | * There can be only one {@link XmlAnyElement} annotated JavaBean property |
ohair@286 | 78 | * in a class and its super classes. |
ohair@286 | 79 | * |
ohair@286 | 80 | * <h2>Relationship to other annotations</h2> |
ohair@286 | 81 | * <p> |
ohair@286 | 82 | * This annotation can be used with {@link XmlJavaTypeAdapter}, so that users |
ohair@286 | 83 | * can map their own data structure to DOM, which in turn can be composed |
ohair@286 | 84 | * into XML. |
ohair@286 | 85 | * |
ohair@286 | 86 | * <p> |
ohair@286 | 87 | * This annotation can be used with {@link XmlMixed} like this: |
ohair@286 | 88 | * <pre> |
ohair@286 | 89 | * // List of java.lang.String or DOM nodes. |
ohair@286 | 90 | * @XmlAnyElement @XmlMixed |

ohair@286 | 129 | * |
ohair@286 | 130 | * |
ohair@286 | 131 | * The following schema would produce the following Java class: |

ohair@286 | 172 | * |
ohair@286 | 173 | * <p> |

ohair@286 | 226 | * } |
ohair@286 | 227 | * </pre> |
ohair@286 | 228 | * then the following document will unmarshal like this: |
ohair@286 | 229 | * <pre> |
ohair@286 | 230 | * <foo> |
ohair@286 | 231 | * <unknown /> |
ohair@286 | 232 | * <foo /> |

ohair@286 | 235 | * Foo foo = unmarshal(); |
ohair@286 | 236 | * // 1 for 'unknown', another for 'foo' |
ohair@286 | 237 | * assert foo.others.length==2; |
ohair@286 | 238 | * // 'unknown' unmarshals to a DOM element |
ohair@286 | 239 | * assert foo.others[0] instanceof Element; |
