Implementation

github.com

magento/magento2/blob/2.1.7/app/code/Magento/Vault/Model/Method/Vault.php#L483-L489


/**
 * @param OrderPaymentInterface $payment
 * @return \Magento\Sales\Api\Data\OrderPaymentExtensionInterface
 */
private function getPaymentExtensionAttributes(OrderPaymentInterface $payment)
{
    $extensionAttributes = $payment->getExtensionAttributes();

The $payment->getExtensionAttributes() code:

Calls the Magento\Sales\Model\Order\Payment::getExtensionAttributes() method.

Calls the Magento\Vault\Plugin\PaymentVaultAttributesLoad::afterGetExtensionAttributes() after-plugin.

if ($extensionAttributes === null) {
    $extensionAttributes = $this->paymentExtensionFactory->create();
    $payment->setExtensionAttributes($extensionAttributes);
}


return $extensionAttributes;
