简介
bgl_named_params作为graph中的有名参数
定义
宏BOOST_BGL_ONE_PARAM_REF
有两个定义,一个定义在类bgl_named_params中用于定义成员方法,另外一个作为全局方法
bgl_named_params类中的成员方法
#define BOOST_BGL_ONE_PARAM_REF(name, key) \template <typename PType> \bgl_named_params<boost::reference_wrapper<PType>, BOOST_PP_CAT(key, _t), self> \name(PType& p) const { \typedef bgl_named_params<boost::reference_wrapper<PType>, BOOST_PP_CAT(key, _t), self> Params; \return Params(boost::ref(p), *this); \} \
全局方法
#define BOOST_BGL_ONE_PARAM_REF(name, key) \template <typename PType> \bgl_named_params<boost::reference_wrapper<PType>, BOOST_PP_CAT(key, _t)> \name(PType& p) { \typedef bgl_named_params<boost::reference_wrapper<PType>, BOOST_PP_CAT(key, _t)> Params; \return Params(boost::ref(p)); \} \
宏BOOST_BGL_ONE_PARAM_CREF
