["Vermeulen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENJPA-655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13435876#comment-13435876 ] 

Vermeulen commented on OPENJPA-655:
-----------------------------------

Note that the jpasecurity project on sourceforge does something like this in it's @Permit annotation: it allows filtering based on the rights of the current user.

> A class-level query filter that applies to all queries implicitly is a useful functionality and available in similar software product [1].
> The base functionality is:
> a) A class can be annotated with a query
> @Entity
> @Filter(query="SELECT x FROM PObject x WHERE x.field = f1 AND x.status =! DONE")
> public class PObject {...}
> b) Any query on class PObject will augment the class-level filter predicates. 
> c) @Filter query can be parametrized. The parameters can be set on current FetchPlan.
> Will attach a draft/prototype for such functionality. Please take a look and let me know your valued comments.
