The example shows how we could implement the _logout() method. Notice we
check if the user is logged in before attempting to log them out.
/**
* Logs the current user out.
*
* @access private
* @return boolean true on success
*/
function _actionLogout()
{
global $mainframe;
$user =& JFactory::getUser();
if($user->get('id') && $mainframe->logout() )
{
return true;
}
return false;
}
