2. Registry¶

// First you need to create the registry object and tell what kind of interface that you want to work with.
$registry = new ServiceRegistry('Sylius\Component\Pricing\Calculator\CalculatorInterface');

// After that you can register a object.
// The first argument is key which identify your object and the second one is the object that you want to register
$registry->register('volume_based', new VolumeBasedCalculator());
$registry->register('standard', new StandardCalculator());

// You can unregister a object too
$registry->unregister('standard');

// You can check if your object is registered, the following method method return a boolean
$registry->has('volume_based');

// And finally, you can get the instance of your object
$registry->get('volume_based');
