Hi, I'm trying to implement pub/sub like communication model with the following scheme. *pubsub.capnp* *interface EventPublisher{* * interface Subscriber {* * updateEvent @0 (event: Int32) -> ();* * }* * subscribe @0 (subscriber: Subscriber) -> (result: Int32);* * unsubscribe @1 (subscriber: Subscriber) -> (result: Int32);* *}*
I'm using *kj::Vector<EventPublisher::Subscriber::Client> m_subscribers *to store the current subscribers. When I try to implement unsubscribe and remove the Subscriber from the Vector, I couldn't find good method to do that. Could you give me some advice? *server implementation* *class EventPublisherImpl final : public EventPublisher::Server {* * protected:* * ::kj::Promise<void> subscribe(SubscribeContext context) {* * cout << "subscribe request received" << endl;* * m_subscribers.add(context.getParams().getSubscriber());* * return kj::READY_NOW;* * }* * ::kj::Promise<void> unsubscribe(UnsubscribeContext context) {* * cout << "unsubscribe request received" << endl;* * auto unsub = context.getParams().getSubscriber();* * // I want to remove usub from subscribers like m_subscribers[unsub].erase();* * // But I couldn't find a method to compare* * // "EventPublisher::Subscriber::Client" such as == operator or public method* * // to distinguish the client.* * //* * // One solution is having an additional argument(id) for this purpose but* * // that requres additional management of ID.* * // subscribe @0 (subscriber: Subscriber, id: Int32) -> (result: Int32);* * // unsubscribe @1 (id: Int32) -> (result: Int32);* * // what I can do is erase everything but this is not my goal* * m_subscribers.clear();* * return kj::READY_NOW;* * }* * private:* * kj::Vector<EventPublisher::Subscriber::Client> m_subscribers;* *};* Thank you, -- You received this message because you are subscribed to the Google Groups "Cap'n Proto" group.
