Subject [jira] [Commented] (MAHOUT-633) Add SequenceFileIterable; put Iterable stuff in one place
Date Tue, 29 Mar 2011 19:28:05 GMT


Dmitriy Lyubimov commented on MAHOUT-633:

bq. Oh yes, it's already split up that way and one delegates to the other. Ordering is easy
to add. How about I add it to the patch and let you take a look at using it? I say that as
I think it may be better if you have a look at what I changed directly to make sure it makes
sense, and that's a small way of accomplishing this.

Yes sir, i will try to do it in the evening. (My daughter going to sleep routine permitting).

> In another project I have a useful little class, SequenceFileIterable, which simplifies
iterating over a sequence file. It's like FileLineIterable. I'd like to add it, then use it
throughout the code. See patch, which for now merely has the proposed new classes. 
> Well it also moves some other iterator-related classes that seemed to be outside their
rightful home in common.iterator.
