[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-6998?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=45269#comment-45269 ] 

Steve Ebersole commented on HHH-6998:
-------------------------------------

{{DirtyCheckContext}} would need access to {{Session}}, so:

{code:title=CustomEntityDirtinessStrategy.java|borderStyle=solid}
public interface CustomEntityDirtinessStrategy {
    ...
    public void findDirty(DirtyCheckContext context, Object entity);
}
{code}

plus a {{getSession}} method on {{DirtyCheckContext}}

> {{CustomEntityDirtinessStrategy}} allows applications to bypass dirty checking in cases when they know an entity is not dirty.
> In some of these application, they also carry along the initial ("loaded") state.  In those cases it might be more performant to allow them to tell us which fields changed.  If we go this route though I'd like to take it as an opportunity to explore options for not exposing all these arrays to user code.  So partially this issue will be a discussion of possible approaches to that.
