Detailed Description

template<typename TRegisterable>
class ToyMaker::Registrator< TRegisterable >

Helper class for registering a class at program startup.

It accomplishes this by:

• Forcing an implementation of static function registerSelf() using CRTP, called here.
• Ensuring its owner's registerSelf() function is called during the static initialization phase of the program.

Usage:

class YourClass {
 
    // ... the rest of your class definition
    // ...
 
    YourClass() {s_registrator.emptyFunc()} // NOTE: Explicit constructor definition
 
    // NOTE: This function will be called by constructor Registrator<YourClass>()
    static YourReturnType registerSelf() {
 
        // NOTE: Ensure correct order of registration for related classes,
        // hopefully avoiding static initialization order fiasco
 
        Registrator<ClassYouDependOn>::getRegistrator(); //< Calls ClassYouDependOn's registerSelf() in turn.
        Registrator<AnotherClassYouDependOn>::getRegistrator();
 
        // NOTE: ... whatever the class needs to do to actually register itself
        // wherever it needs to be registered
 
    }
 
    // NOTE: Declaration and initialization of the registrator static
    // member associated with your class.
    inline static Registrator<YourClass> s_registrator { Registrator<YourClass>::getRegistrator() };
 
    // ... 
    // The rest of your class definition
 
};
