/**
* 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 ElementCollection
