javax.xml.bind.annotation 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
The @XmlID annotation can be used with the following program elements:- a JavaBean property
- non static, non transient field
See "Package Specification" in javax.xml.bind.package javadoc for additional common information.
The usage is subject to the following constraints:- 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>
