Subject ResetableIterator for Joins
Date Sat, 31 Mar 2012 17:32:43 GMT

I don't quite understand the purpose of the ResetableIterator. (

The description says - This defines an interface to a stateful Iterator
that can replay elements added to it directly. Note that this does not
extend Iterator<http://java.sun.com/javase/6/docs/api/java/util/Iterator.html?is-external=true>.

What's a stateful iterator and why do we need to replay elements added to
it? Why does it not extend Iterator? I would appreciate any insight!

Warm Regards,
Deepak Nettem
