[jira] [Commented] (DERBY-6674) Cleanup brittle code in ValidateCheckConstraintResultSet

["Dag H. Wanvik (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DERBY-6674?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14081149#comment-14081149 ] 

Dag H. Wanvik commented on DERBY-6674:
--------------------------------------

Yes, I was aware of this redundancy. I didn't refactor it yet for fear of a) possible performance impact for the non deferrable constraints code path, and b) I wasn't sure how much of the code I could remove for the simplified use case of getNextRowCore for ValidateCheckConstraintResultSet relative to the general getNextRowCore for TableSCanResultSet. Still, it would be good if we could find a non-impacting way to avoid the redundancy.

> The getNextRowCore() method of ValidateCheckConstraintResultSet is an almost exact cut-and-paste copy of the method it overrides in its superclass. This code should be re-factored to reduce the cut-and-paste brittleness. This was discovered while investigating DERBY-6665.
