Function Documentation

type_info_of() [1/2]

template<typename T>

TypeInfo const & libcwd::type_info_of ( )

inline

This specialization allows to specify a type without an object (for example by calling: type_info_of<int const>()).

As it doesn't ignore top-level qualifiers it is best suited to print for example template parameters. For example,

template<typename T>
void Foo::func(T const&)
{
  Dout(dc::notice, "Calling Foo::func(" << type_info_of<T const&>().demangled_name() << ')');
}

type_info_of() [2/2]

template<typename T>

TypeInfo const & libcwd::type_info_of ( T const & )

inline

This template is used by passing an object to it, top level CV-qualifiers (and a possible reference) are ignored in the same way as does typeid() (see 5.2.8 Type identification of the ISO C++ standard).
