Redis_Client

This static class only reason to exist is to tie Drupal global configuration to OOP driven code of this module: it will handle everything that must be read from global configuration and let other components live without any existence of it

Code

public static function getClientInterfaceName() {
  global $conf;
  if (!empty($conf['redis_client_interface'])) {
    return $conf['redis_client_interface'];
  }
  else {
    if (class_exists('Predis\\Client')) {

      // Transparent and abitrary preference for Predis library.
      return $conf['redis_client_interface'] = 'Predis';
    }
    else {
      if (class_exists('Redis')) {

        // Fallback on PhpRedis if available.
        return $conf['redis_client_interface'] = 'PhpRedis';
      }
      else {
        throw new Exception("No client interface set.");
      }
    }
  }
