Constructor & Destructor Documentation

lass::util::impl::SingletonGuard::~SingletonGuard ( )

on destruction, you have to kill all singletons.

This isn't thread safe as it is, but that's ok because it's only "caller" singletonCleanUp() is already locking on SingletonGuard level for us.

Member Function Documentation

void lass::util::impl::SingletonGuard::subscribe ( SingletonBase * iSingleton )

subscribe singleton to the destruction list

This isn't thread safe as it is, but that's ok because it's only indirect caller Singleton::instance() is already locking on SingletonGuard level for us.
