Runtime class

A Runtime manages the interface to the Lambda API.

The Runtime is designed as singleton and Runtime.instance returns the same instance of the Runtime everytime.

final Handler<AwsS3NotificationEvent> helloWorldHandler =
  (context, event) async {
   return new InvocationResult(context.requestId, "HELLO WORLD");
};

await Runtime.instance
  ..registerHandler<AwsS3NotificationEvent>("hello.world", helloWorld)
  ..invoke();

Methods

deregisterEvent<T>() → void

Deregister an new event to be ingested by a handler. The type should reflect your type in your handler definition Handler<T>.

deregisterHandler(String name) → Handler?

Unregister a handler function Handler with name.

handlerExists(String name) → bool

Checks if a specific handlers has been registered with the runtime.

invoke() → void

Run the Runtime in loop and digest events that are fetched from the AWS Lambda API Interface. The events are processed sequentially and are fetched from the AWS Lambda API Interface.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

registerEvent<T>(T func(Map<String, dynamic>)) → void

Register an new event to be ingested by a handler. The type should reflect your type in your handler definition Handler<T>.

registerHandler<E>(String name, Handler<E> handler) → Handler<E>

Register a handler function Handler<T> with name which digests an event T.

toString() → String

A string representation of this object.
