Mapping Enums

Use the @XmlEnumValue annotation with XmlEnum to map an enum constant in Enum type to XML representation. The @XmlEnumValue annotation can be used with the enum constant element.


Mapping enum constant name

This code:

     @XmlEnum(String.class)
     public enum Card { CLUBS, DIAMONDS, HEARTS, SPADES }

will generate the following XML schema:

     <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>

Mapping enum constant name(value)

This code:

     @XmlType
     @XmlEnum(Integer.class)
     public enum Coin { 
         @XmlEnumValue("1") PENNY(1),
         @XmlEnumValue("5") NICKEL(5),
         @XmlEnumValue("10") DIME(10),
         @XmlEnumValue("25") QUARTER(25) }

will generate the following XML schema:

     <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>
