Subject [jira] [Created] (DERBY-5143) Remove unnecessary copying of the map in getTypeMap()
Date Mon, 21 Mar 2011 00:35:06 GMT
Remove unnecessary copying of the map in getTypeMap()
-----------------------------------------------------

                 Key: DERBY-5143
                 URL: https://issues.apache.org/jira/browse/DERBY-5143
             Project: Derby
          Issue Type: Improvement
          Components: JDBC
    Affects Versions: 10.8.0.0
            Reporter: Knut Anders Hatlen
            Assignee: Knut Anders Hatlen
            Priority: Minor


The JDBC 4.0 Connection classes implement getTypeMap() by calling super.getTypeMap() and copying
the resulting map. This is done to prevent an unchecked compiler warning that we would see
if we simply returned super.getTypeMap() in this method. It would be cheaper and simpler to
return super.getTypeMap() and ignore the warning.
