// ... This is not supported in standard C++.
In C++, standard type traits like std::is_class
and std::is_function
already provide most of the functionality needed to check if a type is a class or function, so for is_class
and is_function
, this code simply derives from the appropriate standard trait.
For containers like vector
, set
, and map
, the element_type
structure provides a way to extract the type of the elements stored in the container. For example, for a std::map<Key, Value>
, it gives you std::pair<const Key, Value>
, which is the type of the elements stored within a map.
Checking if a type is primitive is done with specializations for each primitive type, which derive from std::true_type
to indicate that the type is indeed primitive.
However, C++ does not provide a direct way to introspect classes to get base classes, member functions, or member variables. Some of this functionality can be achieved using external libraries or compiler-specific extensions, but they are not part of the C++ standard.
Lastly, note that using using namespace std;
is often considered bad practice in header files or at a global scope in source files, because it introduces the entire standard library into the global namespace, which can lead
