Passkey

#include "Saturn/Core/Passkey.h"

A passkey helps restrict certain functions to certain classes, allowing that only class "Ty" can use the function.

template<typename Ty>
class Passkey

This helps us avoid using "friend class Ty" in the class itself because friend classes are an "all or nothing" solution.

Public members

There are no public members.

Usage

void MyClass::DoSomeShit( Passkey<MyOtherClass> pk ) 
{
    ...code...
}

// And use as such:
m_pMyClass->DoSomeShit( Passkey<MyOtherClass>() );
