示例1: BestMatch

int CAEChannelInfo::BestMatch(const std::vector<CAEChannelInfo>& dsts, int* score) const
{
  CAEChannelInfo availableDstChannels;
  for (unsigned int i = 0; i < dsts.size(); i++)
    availableDstChannels.AddMissingChannels(dsts[i]);

  /* if we have channels not existing in any destination layout but that
   * are remappable (e.g. RC => RL+RR), do those remaps */
  CAEChannelInfo src(*this);
  src.ResolveChannels(availableDstChannels);

  bool remapped = (src != *this);
  /* good enough approximation (does not account for added channels) */
  int dropped = std::max((int)src.Count() - (int)Count(), 0);

  int bestScore = std::numeric_limits<int>::min();
  int bestMatch = -1;

  for (unsigned int i = 0; i < dsts.size(); i++)
  {
    const CAEChannelInfo& dst = dsts[i];
    int okChannels = 0;

    for (unsigned int j = 0; j < src.Count(); j++)
      okChannels += dst.HasChannel(src[j]);

    int missingChannels = src.Count() - okChannels;
    int extraChannels = dst.Count() - okChannels;

    int curScore = 0 - (missingChannels + dropped) * 1000 - extraChannels * 10 - (remapped ? 1 : 0);

    if (curScore > bestScore)
    {
      bestScore = curScore;
      bestMatch = i;
      if (curScore == 0)
        break;
    }
  }

  if (score)
    *score = bestScore;

  return bestMatch;
}
