Subject [jira] Created: (SANDBOX-279) CSVStrategy has modifiable public static variables
Date Sun, 08 Feb 2009 02:54:59 GMT
CSVStrategy has modifiable public static variables
--------------------------------------------------

                 Key: SANDBOX-279
                 URL: https://issues.apache.org/jira/browse/SANDBOX-279
             Project: Commons Sandbox
          Issue Type: Improvement
          Components: CSV
    Affects Versions: Nightly Builds
            Reporter: Bob Smith
            Priority: Minor


The public static variables in CSVStrategy are not final and DEFAULT_STRATEGY, EXCEL_STRATEGY,
and TDF_STRATEGY can be modified using setter methods.  I would recommend making them all
final and using an unmodifiable subclass for the CSVStrategy variables.   

For this change to work, the main CSVStrategy constructor would have to be changed to set
the class fields directly instead of using the setters since the unmodifiable subclass will
have overwritten all of the setters to thrown UnsupportedOperationExceptions.  And I think
a copy constructor would also be a good addition to allow easily copying one of these (or
any) CSVStrategy objects if any modifications have to be made to them (as an alternative to
the clone method).
