/**
 * Specifies that a persistent property or field should be persisted
 * as a enumerated type.  The Enumerated annotation may
 * be used in conjunction with the Basic annotation, or in
 * conjunction with the ElementCollection annotation when the
 * element collection value is of basic type.  If the enumerated type
 * is not specified or the Enumerated annotation is not
 * used, the EnumType value is assumed to be ORDINAL.
 *
 *  *   Example:
 *
 *   public enum EmployeeStatus {FULL_TIME, PART_TIME, CONTRACT}
 *
 *   public enum SalaryRate {JUNIOR, SENIOR, MANAGER, EXECUTIVE}
 *
 *   @Entity public class Employee {
 *       public EmployeeStatus getStatus() {...}
 *       ...
 *       @Enumerated(STRING)
 *       public SalaryRate getPayScale() {...}
 *       ...
 *   }
 * 
 *
 * @see Basic
 * @see ElementCollection
 *
 * @since Java Persistence 1.0
