Subject [jira] Commented: (OPENJPA-1541) Support Enum as Primary Key Type
Date Tue, 21 Sep 2010 08:28:32 GMT


Marc Logemann commented on OPENJPA-1541:

Is this documented somwhere in the JPA docs that the enum ID feature is gone. I ve read a
document where all the "changes" (from 1.x to 2.x) are documented but i cant remember reading
something about Enums.

> Enums work as primary keys in TopLink and EclipseLink. DataNucleus supports them, too:
> It would be good to also include this in the specification because, not to support type
safety in primary keys is fairly sad.
> Enum is a basic language feature, and most applications would enjoy significant benefits
by mapping the keys of those little system behavior controlling lookup tables to enums.
> Consider a payment_type table. One can only generate the IDs of the table and use them
for switching safely when the ids are mapped to enums. Any such application would typically
have a PaymentType enum anyway.
