Re: [eclipselink-users] Converters for non-basic types
|
Hi Andreas,
I'm afraid I don't know Scala. 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.

Hi.
Is it possible to have converters for @{Many,One}ToOne relations?
I have a project in Scala and use Option whereever I can on basic-types, having
appropriate converters for Option[DateTime], Option[Int] etc. but would like to
use Option instead of null for relations.
I know I can get around it by having getters/setters wrapping the private
mappings and use field-based mappings but accessors for manipulation, like this:
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name =*"project_id"*)
*private*[*this*]*var**/project/*:*Project*=*null
**def*projectOpt =/Option/(*/project/*)
*def*projectOpt_=(newVal:*Option*[*Project*]) {*/project/*= newVal.orNull}
But it would be cool if one could write:
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name =*"project_id"*)
@Convert(converter = classOf[ProjectOptionConverter])
*var**/project/*:*Option*[*Project*] =None
This is not possible in Hibernate, is it possible in EclipseLink?
Thanks.
