VideoTape - Video

VideoSimple.cs

// In its simplest form
public class VideoTape {
  // as purely constructor injection of a "parent"
  public VideoTape(Video video) {
    _video = video;
  }
}

public class VideoTape : IVideoObjectInheritor {
  // as a hidden-from-the-public-eye method based injection
  void IVideoObjectInheritor.InheritFrom(Video video) {
    _video = video;
  }
}

public class VideoTape {
  // as part of an event sourced rehydration/materialization process
  public void LoadFromHistory(Video video, IEnumerable<object> events) {
    _video = video;
    foreach(var @event in events)
      Replay(@event);
  }
}
