/**
 * This annotation is used to map a back-pointer during the unmarshal operation.
 * When configuring an @XmlInverseReference, the "mappedBy" attribute must
 * be set to the field on the reference class that maps to this field.  For
 * example:

* * *  @XmlRootElement
*  public class Employee {
*     ...
*     @XmlElementWrapper(name="phone-numbers")
*     @XmlElement(name="number")
*     public List<PhoneNumber> phoneNumbers;
*     ...
*  }

* *  public class PhoneNumber {
*     ...
*     @XmlInverseReference(mappedBy="phoneNumbers")
*     public Employee owningEmployee;
*     ...
*  }
*
* *

By default using @XmlInverseReference will make the property act the * same as @XmlTransient for the marshal operation. You can make the * property writeable by combining it will @XmlElement.

* *  public class PhoneNumber {
*     ...
*     @XmlInverseReference(mappedBy="phoneNumbers")
*     @XmlElement
*     public Employee owningEmployee;
*     ...
*  }
*
*/ @Target({ElementType.FIELD, ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) public @interface XmlInverseReference { String mappedBy(); }
