示例1: read_tile_or_closest_ancestor

bool Channel::read_tile_or_closest_ancestor(TileIndex ti, TileIndex &ret_index, Tile &ret) const {
  Locker lock(*this);  // Lock self and hold lock until exiting this method
  ChannelInfo info;
  bool success = read_info(info);
  if (!success) {
    if (verbosity) log_f("read_tile_or_closest_ancestor: can't read info");
    return false;
  }
  TileIndex root = info.nonnegative_root_tile_index;

  if (ti.is_ancestor_of(root)) {
    ret_index = root;
  } else {
    if (ti != root && !root.is_ancestor_of(ti)) {
      // Tile isn't under root
      return false;
    }
    
    assert(tile_exists(root));
    ret_index = root;
    while (ret_index != ti) {
      TileIndex child = ti.start_time() < ret_index.left_child().end_time() ? ret_index.left_child() : ret_index.right_child();
      if (!tile_exists(child)) break;
      ret_index = child;
    }
  }
  // ret_index now holds closest ancestor to ti (or ti itself if it exists)  
    
  assert(read_tile(ret_index, ret));
  return true;

示例2: find_successive_tile

TileIndex Channel::find_successive_tile(TileIndex root, TileIndex ti, int desired_level) const {
  // Move upwards until parent has a different end time
  while (1) {
    if (ti.parent().is_null()) return TileIndex::null();
    if (ti.parent().end_time() != ti.end_time()) break;
    ti = ti.parent();
    if (ti.level >= root.level) {
      // No more underneath the root
      return TileIndex::null();
    }
  }
  // We are now the left child of our parent;  skip to the right child
  ti = ti.sibling();

  return find_child_overlapping_time(ti, ti.start_time(), desired_level);
}
