Defined in header <typeindex>
class type_index;
(since C++11)

The type_index class is a wrapper class around a std::type_info object, that can be used as index in associative and unordered associative containers. The relationship with type_info object is maintained through a pointer, therefore type_index is CopyConstructible and CopyAssignable.

[edit] Member functions

constructs the object
(public member function) [edit]
compares the underlying std::type_info objects
(public member function) [edit]
returns hashed code
(public member function) [edit]
returns implementation defined name of the type,
associated with underlying type_info object
(public member function) [edit]
