Data Reader Pattern??

[Vijay Kashyap]

I came across an Abstract class DataReader which looks like.

 
 
abstract boolean next() ;
abstract List getRowData();
abstarct void exit();
 
.
.
.
.
other methods
   

There are few different implementation of this abstract class used in application.


Can anyone tells me it is any sort of Design pattern?

Vijay

Peer,

Thanks for the links.

I came across a post (donot remember which forum) that highlights a pretty nice solution for data traversing where by callee will handle all SQLExceptions and take appropriate actions. That interface looks similar to the one I have described.

I need some more feedback as to why and when one should use this approach.

Is it making any sense, Whatever I have written.
