Modify or Extends Data class

[dennis hu]

Hi Mark and other guys:
In my implementation, I just modify the deprecated methods in Data class and add a little codes to verify the database file in his constructor.
I think the Data object is functional and effictively,I donot want to modify his main function, so create a new Remote Class have a reference refer to the Data object, I impletments the lock/unlock,findCriteria method in my remote oject.
Maybe means I had modified the Data class, but could somebody tell me its advantage and disadvantage??
Thanks!

Hi,
I did both, modified the Data class adding the searching functionality and extended it like you did for Remote connections and added my locking here. In my opinion this is a logical approach, because you have to distinguish local and remote connections. Local clients do not need any locking implementation, remote clients do. In my extended class I modified the lock/unlock signatures to support client identification. I guess Sun had no problem with this solution, I passed with 149.
Hope this helps...

Jay,

You mean in your RemoteDataAccess you have a reference refer to the Data object?
