Let's say we have an enum with custom values, used as a persistent field in an entity:

public enum Sex {

 MALE(77),
 FEMALE(99);

 public int getValue() {
 return value;
 }

 int value;

 Sex(int v) {
 value = v;
 }
}

The spec defines two ways to map the enum property with the DB field:

Sex.MALE <=> 0
 Sex.FEMALE <=> 1
 // the default one, i.e. the var.ordinal() value

or

Sex.MALE <=> "MALE"
 Sex.FEMALE <=> "FEMALE"
 // using @Enumerated(STRING)

That's ok, but is there an easy way to use some kind of custom mapping?

In this case:

Sex.MALE <=> 77
 Sex.FEMALE <=> 99
 // i.e. the user-defined var.getValue() result
