The "cxxstd" json field is being added to each Boost library's meta json information for libraries in order to specify the minumum C++ standard compilation level. The value of this field matches one of the values for 'cxxstd' in Boost.Build. The purpose of doing this is to provide information for the Boost website documentation for each library which will specify the minimum C++ standard compilation that an end-user must employ in order to use the particular library. This will aid end-users who want to know if they can successfully use a Boost library based on their C++ compiler's compilation level, without having to search the library's documentation to find this out.	2021-01-19 12:48:45 -05:00

Julien DELACROIX	e130cd860c	boost::polymorphic_downcast only supports raw pointer cast, which is a gap compared to static_cast. To make it clear: Base* base = new Base(); static_cast<Derived>(base) ===> OK static_cast<Derived&>(base) ===> OK boost::polymorphic_downcast<Derived>(base) ===> OK boost::polymorphic_downcast<Derived&>(base) ===> IMPOSSIBLE boost::polymorphic_downcast being a kind of "debug-safe version" of static_cast, it should provide the same capabilities. This patch extend boost::polymorphic_downcast to support references just like static_cast does. This is achieved by introducing a partial specialization for references. Unit tests have been updated accordingly.	2019-12-09 08:51:10 +01:00
