| /** |
| * Maps an enum constant in {@link Enum} type to XML representation. |
| * |
| * <p> <b>Usage</b> </p> |
| * |
| * <p> The {@code @XmlEnumValue} annotation can be used with the |
| * following program elements: |
| * <ul> |
| * <li>enum constant</li> |
| * </ul> |
| * |
| * <p>See "Package Specification" in javax.xml.bind.package javadoc for |
| * additional common information.</p> |
| * |
| * <p>This annotation, together with {@link XmlEnum} provides a |
| * mapping of enum type to XML representation. |
| * |
| * <p>An enum type is mapped to a schema simple type with enumeration |
| * facets. The schema type is derived from the Java type specified in |
| * {@code @XmlEnum.value()}. Each enum constant {@code @XmlEnumValue} |
| * must have a valid lexical representation for the type |
| * {@code @XmlEnum.value()} |
| * |
| * <p> In the absence of this annotation, {@link Enum#name()} is used |
| * as the XML representation. |
| * |
| * <p> <b>Example 1: </b>Map enum constant name {@literal ->} enumeration facet</p> |
| * <pre> |
| * //Example: Code fragment |
| * @XmlEnum(String.class) |
| * public enum Card { CLUBS, DIAMONDS, HEARTS, SPADES } |
| * {@code |
| * |
| * <!-- Example: XML Schema fragment --> |
| * <xs:simpleType name="Card"> |
| * <xs:restriction base="xs:string"/> |
| * <xs:enumeration value="CLUBS"/> |
| * <xs:enumeration value="DIAMONDS"/> |
| * <xs:enumeration value="HEARTS"/> |
| * <xs:enumeration value="SPADES"/> |
| * </xs:simpleType> |
| * }</pre> |
| * |
| * <p><b>Example 2: </b>Map enum constant name(value) {@literal ->} enumeration facet </p> |
| * <pre> |
| * //Example: code fragment |
| * @XmlType |
| * @XmlEnum(Integer.class) |
| * public enum Coin { |
| * @XmlEnumValue("1") PENNY(1), |
| * @XmlEnumValue("5") NICKEL(5), |
| * @XmlEnumValue("10") DIME(10), |
| * @XmlEnumValue("25") QUARTER(25) } |
| * {@code |
| * |
| * <!-- Example: XML Schema fragment --> |
| * <xs:simpleType name="Coin"> |
| * <xs:restriction base="xs:int"> |
| * <xs:enumeration value="1"/> |
| * <xs:enumeration value="5"/> |
| * <xs:enumeration value="10"/> |
| * <xs:enumeration value="25"/> |
| * </xs:restriction> |
| * </xs:simpleType> |
| * }</pre> |
| * |
| * <p><b>Example 3: </b>Map enum constant name {@literal ->} enumeration facet </p> |
| * |
| * <pre> |
| * //Code fragment |
| * @XmlType |
| * @XmlEnum(Integer.class) |
| * public enum Code { |
| * @XmlEnumValue("1") ONE, |
| * @XmlEnumValue("2") TWO; |
| * } |
| * {@code |
| * |
| * <!-- Example: XML Schema fragment --> |
| * <xs:simpleType name="Code"> |
| * <xs:restriction base="xs:int"> |
| * <xs:enumeration value="1"/> |
| * <xs:enumeration value="2"/> |
| * </xs:restriction> |
