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.
(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_info object 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) |
implementation defined name of the type (public member function) |
(C++11) | wrapper around a type_info object, that can be used as index in associative and unordered associative containers (class) |
typeid | Queries information of a type, returning a std::type_info object representing the type(built-in operator) |
