方法详细资料

minReceiverQueueSize

public int minReceiverQueueSize()

覆盖:

minReceiverQueueSize 在类中 ConsumerImpl<T>

initReceiverQueueSize

public void initReceiverQueueSize()

覆盖:

initReceiverQueueSize 在类中 ConsumerBase<T>

internalReceive

protected Message<T> internalReceive()
                              throws PulsarClientException

覆盖:

internalReceive 在类中 ConsumerImpl<T>

抛出:

PulsarClientException

internalReceiveAsync

protected CompletableFuture<Message<T>> internalReceiveAsync()

覆盖:
