Example 1 with GetMaxOffsetRequestHeader

use of org.apache.rocketmq.common.protocol.header.GetMaxOffsetRequestHeader in project rocketmq by apache.

the class MQClientAPIImpl method getMaxOffset.

public long getMaxOffset(final String addr, final String topic, final int queueId, final long timeoutMillis) throws RemotingException, MQBrokerException, InterruptedException {
