[Olena-patches] [PATCH 04/10] Allow the comparison of faces of different dimensions using `<'.

* mln/topo/face.hh (operator< (const face<D>&, const face<D>&)): Here. This way, a standard container relying on operator< can accept faces of different dimensions. --- milena/ChangeLog | 9 +++++++++ milena/mln/topo/face.hh | 5 ++--- 2 files changed, 11 insertions(+), 3 deletions(-) diff --git a/milena/ChangeLog b/milena/ChangeLog index d49139e..ce5e952 100644 --- a/milena/ChangeLog +++ b/milena/ChangeLog @@ -1,5 +1,14 @@ 2009-04-06 Roland Levillain &lt;roland(a)lrde.epita.fr&gt; + Allow the comparison of faces of different dimensions using `<'. + + * mln/topo/face.hh (operator< (const face<D>&, const face<D>&)): + Here. + This way, a standard container relying on operator< can accept + faces of different dimensions. + +2009-04-06 Roland Levillain &lt;roland(a)lrde.epita.fr&gt; + Add some simple triangle meshes. * mesh/one-triangle.off: diff --git a/milena/mln/topo/face.hh b/milena/mln/topo/face.hh index 74077f1..9c9872f 100644 --- a/milena/mln/topo/face.hh +++ b/milena/mln/topo/face.hh @@ -405,9 +405,8 @@ namespace mln { // Ensure LHS and RHS belong to the same complex. mln_precondition(lhs.cplx() == rhs.cplx()); - // Ensure LHS and RHS have the same dimension. - mln_precondition(lhs.n() == rhs.n()); - return lhs.face_id() < rhs.face_id(); + return lhs.n() < rhs.n() || + (lhs.n() == rhs.n() && lhs.face_id() < rhs.face_id()); } -- 1.6.1.2
