Assuming that the PersistenceManager is thread-safe, it should be very easy
to crib from ScalaJPA to make a ScalaJDO. Off the top of my head:
import javax.jdo.PersistenceManager
trait JDOFactory {
protected def openPM () : PersistenceManager
protected def closePM (toClose : PersistenceManager) : Unit
}
trait ScalaPersistenceManager {
protected def pm : PersistenceManager
// define Scala-ish analogues for PersistenceManager, if needed
...
}
trait RequestVarPM extends JDOFactory with ScalaPersistenceManager {
object pmVar extends
RequestVar[PersistenceManager](openPersistenceManager()) {
this.registerGlobalCleanupFunc(ignore => closePM(this.is))
}
protected def pm = pmVar.is
}
Just a rough sketch, but that would allow you to do:
object Model extends RequestVarPM
And then have a per-request PersistenceManager
