How it works...
The Boost library has a lot of functions for smart pointer conversions. All of them accept a smart pointer and a template parameter T, where T is the desired template type of the smart pointer. Those conversion operator mimic the behavior of built-in casts while correctly managing the reference counting and other smart pointer internals:
- boost::static_pointer_cast<T>(p) - does static_cast<T*>(p.get())
- boost::dynamic_pointer_cast<T>(p) - does dynamic_cast<T*>(p.get())
- boost::const_pointer_cast<T>(p) - does const_cast<T*>(p.get())
- boost::reinterpret_pointer_cast<T>(p) - does reinterpret_cast<T*>(p.get())
