The class type_info holds implementation-specific information about a type, including the name of the type and means to compare two types for equality or collating order. This is the class returned by the typeid operator.

The type_info class is neither CopyConstructible nor CopyAssignable.

Member functions

(constructor)
[deleted]
has neither default nor copy constructors
(public member function)
[virtual]
derived objects are safe to delete through pointer-to-base
(virtual public member function)
operator=
[deleted]
can not be copy-assigned
(public member function)
checks whether the objects refer to the same type
(public member function) [edit]
checks whether the referred type precedes referred type of another type_index
object in the implementation defined order, i.e. orders the referred types
(public member function) [edit]
(C++11)
returns a value which is identical for the same types
(public member function) [edit]
implementation defined name of the type
(public member function) [edit]
