(p_apply): New helper for binary point-wise apply. * tests/pw/tests/apply-binary: New test. * oln/core/abstract/size.hh (oln_size_type_from_2): Adjust macro to new Metalic logic system. * oln/core/pw/abstract/binary_function.hh (binary_function_helper < any_size, any_size >): New specialization. * oln/core/any/point.hh (impl_plus, impl_minus, impl_nth): Implement (as dummies). * oln/core/any/grid.hh (any_coord): Define this type. * oln/core/any/dpoint.hh: Aesthetic changes. * oln/makefile.src (OLN_DEP): Remove core/abstract/regular_niter.hh, core/3d/fwd_niter3d.hh and core/3d/fwd_qiter3d.hh. 2005-04-14 Roland Levillain <roland@lrde.epita.fr> Index: olena/tests/pw/tests/apply-binary --- olena/tests/pw/tests/apply-binary (revision 0) +++ olena/tests/pw/tests/apply-binary (revision 0) @@ -0,0 +1,20 @@ + // -*- C++ -*- +#include <iostream> + +#include <cmath> +#include <oln/core/pw/apply.hh> +#include <oln/core/pw/literal.hh> +#include <oln/core/any/point.hh> + +using namespace oln; + +bool check() +{ + any_point p; + + pw::literal<int> pv1 (p_lit(1)); + pw::literal<int> pv2 (p_lit(2)); + + int res = p_apply(mlc::make_binary_fun(std::plus<int>()), pv1, pv2)(p); + return not (res == 3); +} Index: olena/oln/core/abstract/size.hh --- olena/oln/core/abstract/size.hh (revision 151) +++ olena/oln/core/abstract/size.hh (working copy) @@ -41,7 +41,8 @@ -# define oln_size_type_from_2(S1, S2) typename mlc::if_< typename mlc::eq< S2, oln::any_size >::ret, S1, S2 >::ret +# define oln_size_type_from_2(S1, S2) \ +typename mlc::if_< mlc::eq< S2, oln::any_size >, S1, S2 >::ret Index: olena/oln/core/pw/abstract/binary_function.hh --- olena/oln/core/pw/abstract/binary_function.hh (revision 151) +++ olena/oln/core/pw/abstract/binary_function.hh (working copy) @@ -100,6 +100,14 @@ } }; + template <> + struct binary_function_helper < any_size, any_size > { + template <typename L, typename R> + static const L& select(const L& l, R) { + return l; + } + }; + } // end of namespace oln::pw::abstract::internal Index: olena/oln/core/pw/apply.hh --- olena/oln/core/pw/apply.hh (revision 151) +++ olena/oln/core/pw/apply.hh (working copy) @@ -30,6 +30,7 @@ # include <mlc/fun.hh> # include <oln/core/pw/abstract/function.hh> +# include <oln/core/pw/abstract/binary_function.hh> # include <oln/core/pw/macros.hh> @@ -41,8 +42,7 @@ // fwd decl namespace pw { - template <typename F, typename T> - struct apply; + template <typename F, typename T> struct apply; } // super type @@ -110,18 +110,86 @@ } // end of namespace oln::pw + + /*---------. + | Binary. | + `---------*/ + + // fwd decl + namespace pw { + template <typename F, typename T1, typename T2> struct apply2; + } + + // super type + template <typename F, typename T1, typename T2> + struct set_super_type < pw::apply2<F, T1, T2> > + { + typedef pw::abstract::binary_function<T1, T2, pw::apply2<F, T1, T2> > ret; + }; + + // props + template <typename F, typename T1, typename T2> + struct set_props < category::pw, pw::apply2<F, T1, T2> > + { + typedef typename F::result_type value_type; + }; + + namespace pw { + + template <typename F, typename T1, typename T2> + struct apply2 : + public abstract::binary_function <T1, T2, apply2<F, T1, T2> > + { + typedef apply2<F, T1, T2> self_type; + + typedef oln_pw_type_of(self_type, point) point_type; + typedef oln_pw_type_of(self_type, value) value_type; + typedef oln_pw_type_of(self_type, size) size_type; + + typedef + abstract::binary_function <T1, T2, apply2<F, T1, T2> > super_type; + + F f_; + + apply2(const mlc::abstract::binary_function<F>& f, + const abstract::function<T1>& left, + const abstract::function<T2>& right) : + super_type(left, right), + f_(f.exact()) + { + } + + const value_type impl_get(const point_type& p) const + { + return f_(this->left(p), this->right(p)); + } + }; + + } // end of namespace oln::pw + } // end of namespace oln /// apply function on pwf template <typename F, typename T> -oln::pw::apply<F, T> p_apply (const mlc::abstract::unary_function<F>& f, +oln::pw::apply<F, T> +p_apply (const mlc::abstract::unary_function<F>& f, const oln::pw::abstract::function<T>& x) { oln::pw::apply<F, T> tmp(f, x); return tmp; } +template <typename F, typename T1, typename T2> +oln::pw::apply2<F, T1, T2> +p_apply (const mlc::abstract::binary_function<F>& f, + const oln::pw::abstract::function<T1>& x, + const oln::pw::abstract::function<T2>& y) +{ + oln::pw::apply2<F, T1, T2> tmp(f, x, y); + return tmp; +} + #endif // !
