Table of Contents
Sometimes getting and storing information about a type at runtime is required.
For such cases a construction like &typeid(T)
or C++11 class std::type_index
is usually used, which is where problems start:
typeid(T)
and
std::type_index
require Run Time Type Info
(RTTI)
typeid(T)
erroneously do not strip const, volatile and references from type
std::type_info
objects across shared libraries
std::type_index
Boost.TypeIndex library was designed to work around all those issues.
