[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5499) Extend AuditReader interface with findRevisions() method

[Erik-Berndt Scheper (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5499?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=38174#action_38174 ] 

Erik-Berndt Scheper commented on HHH-5499:
------------------------------------------

With hindsight, a better approach would be to keep the correlation between the revision number and the revision-entity. 
Therefore the new signature of the method should be:

* <T> Map<Number, T> findRevisions(Class<T> revisionEntityClass, Set<Number> revisions)

> Extend AuditReader interface with findRevisions() method

> To improve performance, it would be benificial to extend the Envers AuditReader interface with the following method, so that a list of revision-entities can be retrieved in one query:
> * {{<T> List<T> findRevisions(Class<T> revisionEntityClass, Set<Number> revisions)}}
> See attached patch, with testcases and updated findRevision() method.
