Annotation Type XmlID

Maps a JavaBean property to XML ID.

To preserve referential integrity of an object graph across XML serialization followed by a XML deserialization, requires an object reference to be marshalled by reference or containment appropriately. Annotations @XmlID and @XmlIDREF together allow a customized mapping of a JavaBean property's type by containment or reference.

Usage

• a JavaBean property
• non static, non transient field

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

• At most one field or property in a class can be annotated with @XmlID.
• The JavaBean property's type must be java.lang.String.
• The only other mapping annotations that can be used with @XmlID are:@XmlElement and @XmlAttribute.

Example: Map a JavaBean property's type to xs:ID

    // Example: code fragment
    public class Customer {
        @XmlAttribute
        @XmlID
        public String getCustomerID();
        public void setCustomerID(String id);
        .... other properties not shown
    }

    <!-- Example: XML Schema fragment -->
    <xs:complexType name="Customer">
      <xs:complexContent>
        <xs:sequence>
          ....
        </xs:sequence>
        <xs:attribute name="customerID" type="xs:ID"/>
      </xs:complexContent>
    </xs:complexType>
