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] |
the virtual destructor makes type_info a polymorphic class (virtual public member function) |
| operator= [deleted] |
can not be copy-assigned (public member function) |
| (removed in C++20) |
checks whether the objects refer to the same type (public member function) |
checks whether the referred type precedes referred type of another type_infoobject in the implementation defined order, i.e. orders the referred types (public member function) | |
| (C++11) |
returns a value which is identical for the same types (public member function) |
