Detailed Description

Object that gets notified when a given observable changes.

Member Function Documentation

virtual void update () [pure virtual]This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.
