cleanup-2008 2406: Conversions from proxies keep the possible reference.

by Thierry Geraud

https://svn.lrde.epita.fr/svn/oln/branches/cleanup-2008/milena Index: ChangeLog from Thierry Geraud <thierry.geraud(a)lrde.epita.fr> Conversions from proxies keep the possible reference. * mln/core/concept/proxy.hxx (get_proxy_impl::operator): New overload (mutable) conversion towards the immediate subject. Keep ref or ptr in conversion return type. * mln/core/concept/site_proxy.hh (operator site): De-activate the static check of its presence since "site" can be either a ref, a const ref, or a plain type. * mln/core/concept/accumulator.hh (result_): Update. * mln/core/dpoints_pixter.hh (get_adr): Replace by conversion. Add a static check about the p_ref argument type. * mln/core/internal/site_relative_iterator_base.hh: Likewise. * mln/metal/fix_return.hh: New. core/concept/accumulator.hh | 5 +- core/concept/proxy.hxx | 14 +++++ core/concept/site_proxy.hh | 5 +- core/dpoints_pixter.hh | 6 ++ core/internal/site_relative_iterator_base.hh | 6 +- metal/fix_return.hh | 64 +++++++++++++++++++++++++++ 6 files changed, 90 insertions(+), 10 deletions(-) Index: mln/core/concept/proxy.hxx --- mln/core/concept/proxy.hxx (revision 2405) +++ mln/core/concept/proxy.hxx (working copy) @@ -37,6 +37,7 @@ # include <mln/metal/unconst.hh> # include <mln/metal/is_not_ref.hh> # include <mln/metal/ref.hh> +# include <mln/metal/fix_return.hh> namespace mln @@ -265,7 +266,9 @@ struct get_proxy_impl : helper_get_proxy_impl< Subject, E, mlc_is_a(Subject, Proxy)::value > { - operator mlc_unqualif(Subject) () const; + public: + operator mlc_fix_return(Subject) (); + operator mlc_fix_return(mlc_const_return(Subject)) () const; }; template <typename Subject, typename E> @@ -378,7 +381,7 @@ template <typename Subject, typename E> inline - get_proxy_impl<Subject, E>::operator mlc_unqualif(Subject) () const + get_proxy_impl<Subject, E>::operator mlc_fix_return(mlc_const_return(Subject)) () const { return mln::internal::force_exact<const E>(*this).unproxy_(); @@ -391,6 +394,13 @@ // return *adr; } + template <typename Subject, typename E> + inline + get_proxy_impl<Subject, E>::operator mlc_fix_return(Subject) () + { + return mln::internal::force_exact<E>(*this).unproxy_(); + } + // get_adr Index: mln/core/concept/site_proxy.hh --- mln/core/concept/site_proxy.hh (revision 2405) +++ mln/core/concept/site_proxy.hh (working copy) @@ -86,8 +86,9 @@ const site& (E::*m1)() const = & E::to_site; m1 = 0; - site (E::*m2)() const = & E::operator site; - m2 = 0; + // De-activate because sometimes it returns a "const site&"... +// site (E::*m2)() const = & E::operator site; +// m2 = 0; } # endif // !

[Olena] #166: Revamp util::complex

by Olena

#166: Revamp util::complex -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: enhancement | Status: new Priority: major | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- * As for images, use a `tracked_ptr` to handle the data of the complex, i.e. split the `complex` classe in two: * the complex « shell(s) », holding `tracked_ptr` to shared data; and * the actual complex data (vertices and egdes). Also, handle complexes directly from `p_complex` instead of using a `tracked_ptr`, as copying complexes will become cheap (as for images). * Move complex-related types and routines from `mln/core/` to `mln/topo/`. -- Ticket URL: <https://trac.lrde.org/olena/ticket/166> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.
