/**
 * Specifies a persistent field or property of an entity whose 
 * value is an instance of an embeddable class. The embeddable 
 * class must be annotated as {@link Embeddable}.
 *
 * 

The AttributeOverride, AttributeOverrides, * AssociationOverride, and AssociationOverrides * annotations may be used to override mappings declared or defaulted * by the embeddable class. * *

 *   Example:
 *
 *   @Embedded
 *   @AttributeOverrides({
 *       @AttributeOverride(name="startDate", column=@Column("EMP_START")),
 *       @AttributeOverride(name="endDate", column=@Column("EMP_END"))
 *   })
 *   public EmploymentPeriod getEmploymentPeriod() { ... }
 * 
* * @see Embeddable * @see AttributeOverride * @see AttributeOverrides * @see AssociationOverride * @see AssociationOverrides * * @since Java Persistence 1.0 */ @Target({METHOD, FIELD}) @Retention(RUNTIME) public @interface Embedded { }
