The architecture of this system should separate the iteration across the I/O from the transformation *on* the data. It should also allow the ability to plug-in different transformations at a low-level --- some thought should go into the API of the low-level transformation. Being able to memory-map text files would also be a bonus (but this would require some kind of index to allow seeking through the file).
I have some ideas in this direction, but don't have the time to write them up just yet. -Travis On Feb 27, 2012, at 2:44 PM, Matthew Brett wrote: > Hi, > > On Mon, Feb 27, 2012 at 2:58 PM, Pauli Virtanen <p...@iki.fi> wrote: >> Hi, >> >> 27.02.2012 20:43, Alan G Isaac kirjoitti: >>> On 2/27/2012 2:28 PM, Pauli Virtanen wrote: >>>> ISO specifies comma to be used in international standards >>>> (ISO/IEC Directives, part 2 / 6.6.8.1): >>>> >>>> http://isotc.iso.org/livelink/livelink?func=ll&objId=10562502&objAction=download >>> >>> I do not think you are right. >>> I think that is a presentational requirement: >>> rules of presentation for documents that >>> are intended to become international standards. >> >> Yes, it's an requirement for the standard texts themselves, but not what >> the standard texts specify.
