class PDI::Ref_any< R, W >
A dynamically typed reference to data with automatic memory management and read/write locking semantic.
Ref_any is a smart pointer that features:
- a dynamic type system,
- garbage collection mechanism similar to std::shared_ptr,
- a read/write locking mechanism similar to std::shared_mutex,
- a release system that nullifies all existing references to the raw data,
- a notification system to be notified when a reference is going to be nullified.
