Zend Framework 2 : Check Module Dependency

Zend Framework 2.0.7 and 2.1 were released! They come with new features and more improvements. One of the improvements is ability to check other module already loaded before. It provide Zend\ModuleManager\Feature\DependencyIndicatorInterface.
The sample code is like the following :

namespace Mod2;

use Zend\ModuleManager\Feature\DependencyIndicatorInterface;

class Module implements DependencyIndicatorInterface
{   
    public function getModuleDependencies()
    {
        return array('Mod1');   
    }
    
    public function getConfig() { /* common code here */ }
    public function getAutoloaderConfig() { /* common code here */ }
}

If Mod1 is not loaded before Mod2, it will show the exception : Module “Mod2″ depends on module “Mod1″
