Code

public function flush($cache_bin = '') {

  // No point in performing any action is we're not connected to memcached.
  if (empty($this->isConnected)) {
    return;
  }

  // Memcached doesn't support the flushing by cache bin because of its
  // architecture. Although we've got a workaround - we include a special
  // int number for every cache bin into the cache key. So as soon as this
  // index changes then key for every item changes and it leads to cache
  // rebuild.
  $this
    ->increaseBinIndex($cache_bin);
