Two classes vs two methods in one class?

Show all headers | View raw

I need an iterator which returns "processed" data (a function applied to the 
unprocessed data received from a DB) and an iterator which return both 
processed an unprocessed data (as a structure having ->processed and -
>unprocessed fields).

Should I make two classes of iterators (probably with a common ancestor) or 
one class of iterators but two methods, one returning processed data and one 
returning both processed and unprocessed?

The first scenario:

$iter1 = FirstIteratorClass;
while($iter1->fetch) { # returns processed data only
  ...
}
$iter2 = SecondIteratorClass;
while($iter2->fetch) { # returns both processed and unprocessed data
  ...
}

The second scenario:

$iter1 = IteratorClass;
while($iter1->fetch) { # returns processed data only
  ...
}
$iter2 = IteratorClass;
while($iter2->fetch_all_data) { # returns both processed and unprocessed 
data
  ...
}
