Annotation Type XmlEnumValue


@Retention(RUNTIME) @Target(FIELD) public @interface XmlEnumValue
Maps an enum constant in Enum type to XML representation.

Usage

The @XmlEnumValue annotation can be used with the following program elements:

  • enum constant

See "Package Specification" in jakarta.xml.bind.package javadoc for additional common information.

This annotation, together with XmlEnum provides a mapping of enum type to XML representation.

An enum type is mapped to a schema simple type with enumeration facets. The schema type is derived from the Java type specified in @XmlEnum.value(). Each enum constant @XmlEnumValue must have a valid lexical representation for the type @XmlEnum.value()

In the absence of this annotation, Enum.name() is used as the XML representation.

Example 1: Map enum constant name -> enumeration facet

    //Example: Code fragment
    @XmlEnum(String.class)
    public enum Card { CLUBS, DIAMONDS, HEARTS, SPADES }


    <!-- 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>

Example 2: Map enum constant name(value) -> enumeration facet

    //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) }


    <!-- 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>

Example 3: Map enum constant name -> enumeration facet

    //Code fragment
    @XmlType
    @XmlEnum(Integer.class)
    public enum Code {
        @XmlEnumValue("1") ONE,
        @XmlEnumValue("2") TWO;
    }


    <!-- Example: XML Schema fragment -->
    <xs:simpleType name="Code">
      <xs:restriction base="xs:int">
        <xs:enumeration value="1"/>
        <xs:enumeration value="2"/>
      </xs:restriction>
    </xs:simpleType>
