Tom Baeyens commented on JBPM-1460:
-----------------------------------

[12:01] <tomb> porcherg: thanks.   what do you think about this: https://jira.jboss.org/jira/browse/JBPM-1460
[12:01] <tomb> ?
[12:01] <tomb> can i remove class ObjectReference and use Descriptors instead ?
[12:02] <tomb> os do you see a downside of that
[12:02] <tomb> or do you see a downside of that
[12:04] <porcherg> tomb: i think it can be removed
[12:04] <tomb> ok
[12:04] <porcherg> maybe there will be a db performance impact
[12:04] <tomb> i'll do it in the next couple of days
[12:04] <tomb> should be minimal
[12:04] <tomb> or even for the better
[12:05] <porcherg> because the descriptor table will have a lot of entries
[12:05] <tomb> with an index on a long column that is not a problem
[12:05] <tomb> index is only maintained during deployment
[12:05] <porcherg> but this will but easier to understand
[12:05] <tomb> don't think so
[12:06] <tomb> as most ObjectReferences will have a descriptor memberfield anyway
[12:06] <porcherg>  but this will be easier to understand
[12:06] <tomb> so it removes an extra indirection
[12:06] <porcherg> i think having only one Descriptor is easier
[12:06] <tomb> ok

> ObjectReference.expression can be replaced by an (to-be-created) ExpressionDescriptor
> ObjectReference.object can be replaced by a ProvidedObjectDescriptor
> WDYT ?
