|Re: [eclipselink-users] Converters for non-basic types|
Hi Andreas,The thing we have that is closest to what you are looking for is a WrapperPolicy on our ClassDescriptor. (and I have to admit I haven't tried to solve your particular problem with it)
With WrapperPolicy, you could define an implementer of our WrapperPolicy interface and get called back when objects are being built and disassembled in order to return an object EclipseLink is aware of from one that EclipseLink is not aware of.

Can you give a description of what you are hoping for. We don't have converters on xToOne relationships, but I am trying to figure out if there is something we can do in our event framework to deal with the issue. Scala's Option is a bit like JAVA8's Optional (http://download.java.net/jdk8/docs/api/java/util/Optional.html) and is a container which may hold a value. It would be very cool if one could write (with JAVA8's Optional): @ManyToOne private Optional<Project> project = Optional.empty() This way one won't have to care about null-reference. -- Andreas Joseph Krogh <andreak@xxxxxxxxxxxx> mob: +47 909 56 963 Senior Software Developer / CTO - OfficeNet AS - http://www.officenet.no Public key: http://home.officenet.no/~andreak/public_key.asc _______________________________________________ eclipselink-users mailing list eclipselink-users@xxxxxxxxxxx https://dev.eclipse.org/mailman/listinfo/eclipselink-users
