> Project: Cayenne

> Affects Versions: 3.0
> Environment: All
> Reporter: Michael Gentry

>
> Current Cayenne support for Java 1.5 enumerations is relatively simplistic.
> Given:
> enum Color { RED, GREEN, BLUE }
> Cayenne will store 0, 1, and 2 (respectively) for a numeric column, or "RED",
> "GREEN", and "BLUE" for a string column. There is no way to specify your own
> values for the enumerations, which is especially important when mapping to an
> existing schema. Also, in the case of numeric types, the order they are
> declared is fragile. If someone later sorts the colors to be BLUE, GREEN,
> RED, then the values of BLUE and RED will be swapped (and incorrect) on
> future reads from the database.
> Cayenne needs to be able to support explicitly mapping the enumeration to the
> database value.
