https://svn.lrde.epita.fr/svn/oln/trunk/milena Index: ChangeLog from Thierry Geraud &lt;thierry.geraud(a)lrde.epita.fr&gt; Clean some operators on object and value types. * tests/value_interop.cc (int_u<n>): Augment. Deactivate some parts of code because they contain too few tests to be relevant; they have to be augmented! * tests/value_int_u8.cc: Augment. * tests/hexa.cc: Fix; make it compile. * mln/core/ops.hh (++, --): New operator default impls. * mln/core/concept/value.hh (++, --): Move to... * mln/value/concept/scalar.hh: ...here. Those ops are only relevant for scalars. * mln/value/int_s.hh, * mln/value/int_u.hh (+=, -=): Move to... * mln/value/concept/integer.hh: ...here. Their definition is more general than just for int_*. mln/core/concept/value.hh | 22 -------- mln/core/ops.hh | 32 ++++++++++++ mln/value/concept/integer.hh | 2 mln/value/concept/scalar.hh | 77 +++++++++++++++++++++++++++++ mln/value/int_s.hh | 26 --------- mln/value/int_u.hh | 26 --------- tests/hexa.cc | 7 +- tests/value_int_u8.cc | 78 ++++++++++++++++++++++++++--- tests/value_interop.cc | 114 +++++++++++++++++++++++-------------------- 9 files changed, 246 insertions(+), 138 deletions(-) Index: tests/value_interop.cc --- tests/value_interop.cc (revision 1274) +++ tests/value_interop.cc (working copy) @@ -39,66 +39,76 @@ { using namespace mln;
