outgoingQueue

工作线程

消息加入等待队列

pendingQueue

服务端

均衡负载接口，用于对zookeeper集群进行均衡负载

<interface>HostProvider

发送消息

<interface>ClientWatchManager

+ materialize(): return Set<Watcher>

ClientCnxnSocketNetty

+ attribute1:type = defaultValue+ attribute2:type- attribute3:type

+ operation1(params):returnType- operation2(params)- operation3()

SendThread

- clientCnxnSocket:type = ClientCnxnSocket+ attribute2:type- attribute3:type

- run(): return void- startConnect(InetSocketAddress addr):return void- primeConnection()- operation3()

将消息转化为事件

ZKWatchManager

sendThread

Zookeeper

- watchManager:ZKWatchManager- hostProvider:HostProvider- cnxn:ClientCnxn

消息检验

回应消息

ZooKeeperThread

EventThread

- waitingEvents:LinkedBlockingQueue<Object>

ClientCnxn

- sendThread :SendThread- eventThread: EventThread- outgoingQueue:LinkedBlockingDeque<Packet>- pendingQueue:Queue<Packet>

ClientCnxnSocket

waitingEvents

ClientCnxnSocketNIO

从等待队列获取消息进行检验

zookeeper

获取事件

获取消息

eventThread
