Examples with WatcherEvent org.apache.zookeeper.proto.WatcherEvent used on opensource projects

Example 1 with WatcherEvent

use of org.apache.zookeeper.proto.WatcherEvent in project zookeeper by apache.

the class NIOServerCnxn method process.

/*
     * (non-Javadoc)
     *
     * @see org.apache.zookeeper.server.ServerCnxnIface#process(org.apache.zookeeper.proto.WatcherEvent)
     */
@Override
public void process(WatchedEvent event) {
    ReplyHeader h = new ReplyHeader(ClientCnxn.NOTIFICATION_XID, -1L, 0);
    if (LOG.isTraceEnabled()) {
        ZooTrace.logTraceMessage(LOG, ZooTrace.EVENT_DELIVERY_TRACE_MASK, "Deliver event " + event + " to 0x" + Long.toHexString(this.sessionId) + " through " + this);
    }
    // Convert WatchedEvent to a type that can be sent over the wire
    WatcherEvent e = event.getWrapper();
    // The last parameter OpCode here is used to select the response cache.
    // Passing OpCode.error (with a value of -1) means we don't care, as we don't need
    // response cache on delivering watcher events.
    int responseSize = sendResponse(h, e, "notification", null, null, ZooDefs.OpCode.error);
    ServerMetrics.getMetrics().WATCH_BYTES.add(responseSize);
}

Example 2 with WatcherEvent

        new WatchedEvent(wep);
        fail("Was able to create WatchedEvent from bad wrapper");
    } catch (RuntimeException re) {
    // we're good
    }
}

Example 3 with WatcherEvent

        close();
    }
}
