javax.xml.bind.annotation
Annotation Type XmlID


@Retention(value=RUNTIME)
@Target(value={FIELD,METHOD})
public @interface 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

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

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

The usage is subject to the following constraints:

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>
