Example 35 with Packet

use of com.hazelcast.internal.nio.Packet in project hazelcast by hazelcast.

the class EventServiceImpl method sendEvent.

/**
 * Sends a remote event to the {@code subscriber}.
 * Each event segment keeps track of the published event count. On every {@link #eventSyncFrequency} the event will
 * be sent synchronously.
 * A synchronous event means that we send the event as an {@link SendEventOperation} and in case of failure
 * we increase the failure count and log the failure (see {@link EventProcessor})
 * Otherwise, we send an asynchronous event. This means that we don't wait to see if the processing failed with an
 * exception (see {@link RemoteEventProcessor})
