示例1: DeletePoint

bool RectangleTree<MetricType, StatisticType, MatType, SplitType, DescentType>::
    DeletePoint(const size_t point)
{
  // It is possible that this will cause a reinsertion, so we need to handle the
  // levels properly.
  RectangleTree* root = this;
  while (root->Parent() != NULL)
    root = root->Parent();

  std::vector<bool> lvls(root->TreeDepth());
  for (size_t i = 0; i < lvls.size(); i++)
    lvls[i] = true;

  if (numChildren == 0)
  {
    for (size_t i = 0; i < count; i++)
    {
      if (points[i] == point)
      {
        localDataset->col(i) = localDataset->col(--count); // Decrement count.
        points[i] = points[count];
        // This function wil ensure that minFill is satisfied.
        CondenseTree(dataset->col(point), lvls, true);
        return true;
      }
    }
  }

  for (size_t i = 0; i < numChildren; i++)
    if (children[i]->Bound().Contains(dataset->col(point)))
      if (children[i]->DeletePoint(point, lvls))
        return true;

  return false;
}
