AdapterKeys

Pair framework: AdapterKeys

Pair\Core\AdapterKeys defines the conventional capability names used by AdapterRegistry and application bootstrap. It has constants only and cannot be instantiated.

Constants

Constant	Registry key
CACHE	cache
MAILER	mailer
OBSERVABILITY	observability
PAYMENTS	payments
NOTIFICATIONS	notifications
AI	ai
UI	ui

Registration

use Pair\Core\AdapterKeys;
use Pair\Core\Application;
use Pair\Services\StripeGateway;

$app = Application::getInstance();
$app->setAdapter(AdapterKeys::PAYMENTS, $stripeGateway);

$payments = $app->adapters()->require(AdapterKeys::PAYMENTS, StripeGateway::class);

The registry also accepts application-owned string keys. A constant does not install an integration or load a provider SDK. Application::setAdapter() additionally connects OBSERVABILITY to the observability facade when the adapter implements ObservabilityAdapter. Other keys store adapters for explicit retrieval; cache stores and UI renderers still require their own registration APIs.
