/**
* Provides for the specification of generation strategies for the
* values of primary keys.
*
* <p>
* The <code>GeneratedValue</code> annotation
* may be applied to a primary key property or field of an entity or
* mapped superclass in conjunction with the {@link Id} annotation.
* The use of the <code>GeneratedValue</code> annotation is only
* required to be supported for simple primary keys. Use of the
* <code>GeneratedValue</code> annotation is not supported for derived
* primary keys.
*
* <pre>
*
* Example 1:
*
* &#064;Id
* &#064;GeneratedValue(strategy=SEQUENCE, generator="CUST_SEQ")
* &#064;Column(name="CUST_ID")
* public Long getId() { return id; }
*
* Example 2:
*
* &#064;Id
* &#064;GeneratedValue(strategy=TABLE, generator="CUST_GEN")
* &#064;Column(name="CUST_ID")
* Long id;
* </pre>
*
* @see Id

* @since Java Persistence 1.0
