## Annotation Type MapKeyTemporal

-     @Target(value={METHOD,FIELD})
      @Retention(value=RUNTIME)
      public @interface MapKeyTemporal

  This annotation must be specified for persistent map keys of type `Date` and `Calendar`. It may only be specified for map keys of these types.

  The `MapKeyTemporal` annotation can be applied to an element collection or relationship of type `java.util.Map` in conjunction with the `ElementCollection`, `OneToMany`, or `ManyToMany` annotation.

           Example:

           @OneToMany
           @MapKeyTemporal(DATE)
           protected java.util.Map<java.util.Date, Employee> employees;
