EventPublisher

Base class for an actor publishing events.

Concrete subclasses must implement receiveEvent which becomes part of the initial behavior, i.e. gets called by the provided receive implementation. Typically receiveEvent would be implemented simply be invoking onEvent which fist appends the received event (message) to the buffer which is limited by the bufferSize paramete – old events are discarded – and then publishes the buffered events up to the total demand if this publisher is active.

ActorPublisherMessage.Request is handled by publishing the buffered events up to the requested demand and other ActorPublisherMessages (e.g. Cancel) stop this actor.

If the heartbeatInterval is defined, a ServerSentEvent.heartbeat will be published if no other event has been received within that interval.

Attention: An implicit view A => ServerSentEvent has to be in scope!

Linear Supertypes

ActorPublisher[ServerSentEvent], Actor, AnyRef, Any

Instance Constructors

new EventPublisher(bufferSize: Int, heartbeatInterval: Duration = Duration.Undefined)(implicit arg0: ToServerSentEvent[A])

bufferSize
the maximum number of events (messages) to be buffered
heartbeatInterval
the interval for heartbeats; if Undefined, which is the default, no heartbeats are published
