Parameters
- array $config = array(0) - Configuration
- unknown $request = NULL
Return Values
- void
Source Code
public function __construct(array $config = [], Request $request = NULL)

// Assing Request
if ($request === NULL)
{
$request = Request::current();
}
$this->_request = $request;
// Assign default Route
$this->_route = $request->route();
// Assign default route params
$this->_route_params = $request->param();
// Add controller and action to route params for routes with variable controllers and actions
$this->_route_params['controller'] = $request->controller();
$this->_route_params['action'] = $request->action();
$this->_route_params['directory'] = $request->directory();

$this->setup($config);
}
public __get(string $key ) (defined in Kohana_Pagination)
Returns a Pagination property.
Parameters

{
return isset($this->$key) ? $this->$key : NULL;
}
public __set(string $key , mixed $value ) (defined in Kohana_Pagination)
Updates a single config setting, and recalculates pagination if needed.
Parameters

public config_group([ string <span class="param" title="Pagination config group; "default" if none given">$group</span> = string(7) "default" ] ) (defined in Kohana_Pagination)
Retrieves a pagination config group from the config file. One config group can refer to another as its parent, which will be recursively loaded.
Parameters
