Public Member Functions
template<typename AfterConstructionCallback>
void	Register (AfterConstructionCallback after_construction)
	Registers a functor to register some resource that will be called after the component is successfully created (including all class descendants) or after the component creation is emulated in unit tests. The functor must return a RAII-style handle object that unregisters the previously registered resource. The returned handle's destructor is called just before the component destructor is called.
void	AfterConstruction ()
	Call all registered functors.
void	BeforeDestruction ()
	Free all unregister previously rgistered resources.

Register()

template<typename AfterConstructionCallback>

void utils::ResourceScopeStorage::Register ( AfterConstructionCallback after_construction )

inline

Registers a functor to register some resource that will be called after the component is successfully created (including all class descendants) or after the component creation is emulated in unit tests. The functor must return a RAII-style handle object that unregisters the previously registered resource. The returned handle's destructor is called just before the component destructor is called.

Note

callback is not called if the component is not created OR any previously registered callback throws an exception.

if you don't have an existing RAII-ish class, but still want to do a cleanup, you might want to use utils::FastScopeGuard to wrap the cleanup function.
