Payment Context
PaymentContext is a model used for resolving available payment methods. The following classes represent the payment context:
\Oro\Bundle\PaymentBundle\Context\PaymentContext- payment context itself, contains data such as shipping address, billing address, customer, customer user, website, payment line items, etc. Implements\Oro\Bundle\PaymentBundle\Context\PaymentContextInterface.\Oro\Bundle\PaymentBundle\Context\PaymentLineItem- a payment line item, contains data such as a product, product unit, quantity, price, payment kit item line items (if a product line item is a kit), etc.\Oro\Bundle\PaymentBundle\Context\PaymentKitItemLineItem- a payment kit item line item, contains data such as a product kit item, product, product unit, quantity, price, etc.
During a checkout PaymentContext object is created by the \Oro\Bundle\CheckoutBundle\Factory\CheckoutPaymentContextFactory, although it is recommended to use \Oro\Bundle\CheckoutBundle\Provider\CheckoutPaymentContextProvider that utilizes memory caching to avoid unnecessary calls to the factory. PaymentLineItem in its turn is created by \Oro\Bundle\PaymentBundle\Context\LineItem\Factory\PaymentLineItemFromProductLineItemFactory. If a PaymentLineItem represents a product kit, then for its kit item line items PaymentKitItemLineItem objects are created by \Oro\Bundle\PaymentBundle\Context\LineItem\Factory\PaymentKitItemLineItemFromProductKitItemLineItemFactory.
Note
PaymentLineItemFromProductLineItemFactory implements \Oro\Bundle\PaymentBundle\Context\LineItem\Factory\PaymentLineItemFromProductLineItemFactoryInterface and PaymentKitItemLineItemFromProductKitItemLineItemFactory - \Oro\Bundle\PaymentBundle\Context\LineItem\Factory\PaymentKitItemLineItemFromProductKitItemLineItemFactoryInterface
The main entry point where PaymentContext is used is \Oro\Bundle\PaymentBundle\Method\Provider\ApplicablePaymentMethodsProvider that delegates further calls to payment methods and payment rules providers.
When it comes to resolving available payment methods, PaymentContext is transformed into a complex array suitable for usage in a payment rule expression by the converter \Oro\Bundle\PaymentBundle\Context\Converter\Basic\BasicPaymentContextToRulesValueConverter.
