Subject Usefulness of ChainMapper/ChainReducer
Date Fri, 28 Sep 2012 13:32:33 GMT
Hi guys,

I have stumbled upon ChainMapper and ChainReducer and I am wondering why
they exist. I imagine that everything you can implement with ChainMapper
and ChainReducer can be implemented with just a Mapper and a Reducer
containing all the code of the respective chain-implementations. Or am I
missing certain aspects about why they are more than just convenience
concepts?

Thanks for clarifying this!
Sigurd
