https://svn.lrde.epita.fr/svn/oln/branches/cleanup-2008/milena Index: ChangeLog from Thierry Geraud <thierry.geraud@lrde.epita.fr> Deactivate site set inclusion tests. Operators that test inclusion relationships between a couple of site sets are not always correct as is. Yet they are widely used thru the library. They are temporarily deactivated thanks to their return value. * mln/util/yes.hh: New utility class that always responds yes, i.e., converts to 'true'. * tests/util/yes.cc: New. * mln/core/concept/site_set.hh (operator==): Deactivate body and return yes. (operator <=): Likewise. (operator <): Likewise. * doc/tutorial/examples/p_array.cc: Add a test of inclusion. doc/tutorial/examples/p_array.cc | 1 mln/core/concept/site_set.hh | 74 +++++++++-------- mln/util/yes.hh | 161 +++++++++++++++++++++++++++++++++++++++ tests/util/yes.cc | 54 +++++++++++++ 4 files changed, 255 insertions(+), 35 deletions(-) Index: tests/util/yes.cc --- tests/util/yes.cc (revision 0) +++ tests/util/yes.cc (revision 0) @@ -0,0 +1,54 @@ +// Copyright (C) 2008 EPITA Research and Development Laboratory +// +// This file is part of the Olena Library.
