javax.persistence Annotation Type Embeddable

@Target(value=TYPE)
@Retention(value=RUNTIME)
public @interface Embeddable

Defines a class whose instances are stored as an intrinsic part of an owning entity and share the identity of the entity. Each of the persistent properties or fields of the embedded object is mapped to the database table for the entity. Only Basic, Column, Lob, Temporal, and Enumerated mapping annotations may portably be used to map the persistent fields or properties of classes annotated as Embeddable.

Note that the Transient annotation may be used to designate the non-persistent state of an embeddable class.
