构造方法详细信息

PullAPIWrapper

public PullAPIWrapper(MQClientInstance mQClientFactory,
                      String consumerGroup,
                      boolean isUnitMode)

方法详细信息

updatePullFromWhichNode

public void updatePullFromWhichNode(MessageQueue mq,
                                    long brokerId)

randomNum

public int randomNum()

processPullResult

public PullResult processPullResult(MessageQueue mq,
                                    PullResult pullResult,
                                    SubscriptionData subscriptionData)

对拉取结果进行处理，主要是消息反序列化

参数：

mq -

pullResult -

subscriptionData -

返回：

recalculatePullFromWhichNode

public long recalculatePullFromWhichNode(MessageQueue mq)

每个队列都应该有相应的变量来保存从哪个服务器拉

pullKernelImpl

public PullResult pullKernelImpl(MessageQueue mq,
                                 String subExpression,
                                 long subVersion,
                                 long offset,
                                 int maxNums,
                                 int sysFlag,
                                 long commitOffset,
                                 long brokerSuspendMaxTimeMillis,
                                 long timeoutMillis,
                                 CommunicationMode communicationMode,
                                 PullCallback pullCallback)
                          throws MQClientException,
                                 RemotingException,
                                 MQBrokerException,
                                 InterruptedException

抛出：
