Re: [vsipl++] Index and Length
- Subject: Re: [vsipl++] Index and Length

Assem,
The code changes look good, but some of the comments appear unnecessary.
In particular, we don't need the comments about how some piece of code
used to use "Point" but now uses "Length/Index". Once "Point" is gone
from a particular section of code, there is no general need to mention
how it used to be implemented. We can get that history from the
changelog and from cvs. Moreover, once we've removed Point from the
library altogether, mentioning it will be confusing.
I don't see any substantive changes to length.hpp. You should revert
your local changes to this file and not commit it.
Some comments misspell 'deprecated".
Finally, I've given some thought to where these functions should go.
The reason that the Point stuff was split out into separate files
point.hpp and point-fcn.hpp was to keep the Point class definition
relatively lightweight so that it could be included without pulling in
the rest of the library. Some of the functions in point-fcn require the
definition of the views (i.e. the extent functions). Including
vector.hpp ends up including quite a bit.
On the surface, worrying about whether point.hpp includes ve,ctor.hpp
might seem silly, since any reasonable VSIPL++ program will end up
including vector.hpp anyway. However, keeping the header dependencies
simple helps improve maintainability. Every so often we make a change
that creates a circular requirement that take some effort to sort out.
Here's what I'd like to do:
- move the view get/put functions from point-fcn.hpp to the respecive
view headers. I.e. get(const_Vector, Index) should go into
vector.hpp. This makes sense becuase if you're going to use get
on a view, you will have to include that view's header. The
view headers should already include domain.hpp, so this doesn't
create a new dependency.
- Move everything else from point.hpp (next, valid, block get/put)
and point-fcn (domain_nth, first, domain constructor helper)
into domain-utils.
How does that sound?

Everyone,
This patch takes out the use of Point and replaces it with Index and
Length.
Thanks,

------------------------------------------------------------------------
2006-03-30 Assem Salama <assem@xxxxxxxxxxxxxxxx>
* src/vsip/impl/length.hpp: Changed the extent function in this file
to return Length instead of point. This extent takes a Block.
* src/vsip/impl/par-util.hpp: Changed the foreach_point function to
work on Index instead of Point.
* src/vsip/impl/point-fcn.hpp: Added new extent functions to return
Length instead of Point.
* src/vsip/impl/point.hpp: Added new functions to make Index and
Length work correctly. The new functions are get,put,next,valid,
and domain_nth.
* tests/appmap.cpp: Converted this test to use Length and Index.
* tests/fast-block.cpp: Same as appmap.cpp
* tests/us-block.cpp: Same as above.
* tests/user_storage.cpp: Same as above.
* tests/util-par.hpp: Same as above.
* tests/view.cpp: Same as above.
* tests/vmmul.cpp: Same as above.
