Hi Thorsten,
Hi Fernando,
Amoung our utilities we have
boost::polymorphic_cast boost::polymorphic_downcast
The latter only performs a check in debug builds, and can then be used whenever the cast must succeed.
Oh... I wasn't aware of _downcast.
boost::numeric_cast has no such alternative. Therefore I wuold like to see one. To keep in the naming convention from above, I think it could be reasonable to call this
boost::numeric_downcast
Furthermore, this should if possible be implemented in a seperate header (which is included in the main header) that can be compiled without exception-support. I think there are still platforms where they need this functionality, but don't want to sue exceptions.
Indeed.. it all makes sense. I'll do it sometimes next week. Best Fernando
