Detailed Description

template<class T>
class jngl::Singleton< T >

Inherit from this class to create a singleton that will be destroyed when your games exits.

You should use this instead of global / static variables, because some platforms (Android) don't destroy the process on exit and instead re-enter the main function.

class Foo : public jngl::Singleton<Foo>
    // ...
}
 
// somewhere else:
Foo::handle().bar();
