XmlEnumValue

Usage

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

• enum constant

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

This annotation, together with {@link 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, {@link 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>
