#include <darts/factory.h>
template<typename Object, typename... Args>
Factory class
Abstract factory used to construct objects by name.
Public static functions
- static auto create_instance(const std::string& name, Args && ... args) -> Object
- Construct an object from the class of the given
nameand passargsto the registered constructor. - static void register_type(const std::string& name, const Constructor constructor)
- Register an object constructor with the object factory.
- static auto registered_types() -> std::set<string>
- Return a set of all classes registered with this factory (useful for debugging).
Protected static functions
- static auto type_registry() -> std::map<std::string, Constructor>&
- Singleton pattern that prevents "static initialization order fiasco".
