Class EventBuffer

java.lang.Object

org.axonframework.axonserver.connector.event.axon.EventBuffer

All Implemented Interfaces:

AutoCloseable, org.axonframework.common.stream.BlockingStream<org.axonframework.eventhandling.TrackedEventMessage<?>>, org.axonframework.eventhandling.TrackingEventStream

public class EventBuffer
extends Object
implements org.axonframework.eventhandling.TrackingEventStream

Client-side buffer of messages received from the server. Once consumed from this buffer, the client is notified of a permit being consumed, potentially triggering a permit refresh, if flow control is enabled.

This class is intended for internal use. Be cautious.

Constructor Detail

EventBuffer

public EventBuffer(io.axoniq.axonserver.connector.event.EventStream delegate,
                   org.axonframework.serialization.upcasting.event.EventUpcaster upcasterChain,
                   org.axonframework.serialization.Serializer serializer,
                   boolean disableEventBlacklisting)

Initializes an Event Buffer, passing messages through given upcasterChain and deserializing events using given serializer.

Parameters:

delegate - the EventStream to delegate operations to

upcasterChain - the upcasterChain to translate serialized representations before deserializing

serializer - the serializer capable of deserializing incoming messages

disableEventBlacklisting - specifying whether events should or should not be included in the buffer
