|Re: [eclipselink-dev] JPA and Scala|
Metadata may be a problem and you would have to address any validation issues as they arose. If the Java impl of Buffer implements List then there may not be any Metadata processing issues.

Hi all, I am working on a JPA wrapper for Scala and I think that I have found an elegant way to use some ideas of JPA. I managed to wrap EntityManager, EntitiyManagerFactory and Query.Unfortunately, there is no simple and elegant way to use Scala's collections. Using Scala classes as entities works fine, as long they are using java.lang.List (and the other collections that are specified).My question is: What would it mean (in terms of effort and knowledge) to allow a Scala collection (f.e. a Buffer) as a OneToMany entity attribute? Regards Christopher PS: Buffer is Scala's mutable "List" implementation (see http://www.scala-lang.org/archives/downloads/distrib/files/nightly/docs/library/scala/collection/mutable/Buffer.html) If you are interested look at http://blog.fakod.eu/?p=855 (description) and http://github.com/FaKod/JPA-for-Scala (code) _______________________________________________ eclipselink-dev mailing list eclipselink-dev@xxxxxxxxxxx https://dev.eclipse.org/mailman/listinfo/eclipselink-dev
