RefCountedObject > <strong>Poco</strong>::RefCountedObject implements thread-safe reference counting semantics. As of 1.3.4 it uses platform-specific atomic operations, if available (Windows, Mac OS X). > Can be used as a base class for classes implementing reference counting. > <strong>Poco</strong>::RefCountedObject has a protected destructor and prohibits copy-construction and assignment. > All reference counted objects should have a protected destructor, to forbid explicit use of delete.
