Choose Distinct Member Function Names When Using Multiple Inheritance

Choose Distinct Member Function Names When Using Multiple Inheritance

When two or more classes serve as base classes in multiple inheritance, you want to choose a distinct name for each member function in order to avoid name ambiguity:

 class AudioStreamer {//real-time sound playerpublic:void Play();void Stop();};  class VideoStreamer {//real-time video playerpublic:void Play();void Stop();}; class AudioVisual: public AudioStreamer, public VideoStreamer {/*_*/};AudioVisual player;player.play(); //error:  is AudioStreamer::play() or VideoStreamer::play() to be invoked?

One way to overcome this ambiguity is to specify the full-qualified name of a member function:

  	Player.AudioStreamer::play(); //fine but tedious

However, a preferable solution is the use of distinct method names in the base classes:

 class AudioStreamer {public:void au_Play(); };  class VideoStreamer {public:void vd_Play(); }; 	Player.au_play(); //now distinct: play sound
