std::type_info - std::type_info


Defined in header <typeinfo>
class type_info;

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 has neither default nor copy constructors
              (public member function)

destructor derived objects are safe to delete through pointer-to-base
              (virtual public member function)

operator= can not be copy-assigned
              (public member function)
              checks whether the objects refer to the same type
operator== (public member function)
              checks whether the referred type precedes referred type of another type_index
before object in the implementation defined order, i.e. orders the referred types
              (public member function)

hash_code returns a value which is identical for the same types
              (public member function)
              implementation defined name of the type
name (public member function)
