Class

spaces_controller

Abstract base class for a spaces controller. Classes that extend spaces_controller must implement load_original_values().

Code

function get($id = NULL, $environment = NULL) {
  if (isset($environment, $id)) {
    $this
      ->load_values($environment, $id);
    return isset($this->values[$environment][$id]) ? $this->values[$environment][$id] : NULL;
  }
  else {
    if (isset($environment)) {
      $this
        ->load_values($environment);
      return isset($this->values[$environment]) ? $this->values[$environment] : NULL;
    }
    else {
      if (isset($id)) {
        $environments = array(
          'space',
          'preset',
          'original',
        );
        $environment = array_shift($environments);
        while (isset($this->values[$environment])) {

        }
        return array();
      }
    }

  // Neither argument provided, return merged set of all values.
