isConnected

public boolean isConnected()

redeliverUnacknowledgedMessages

public void redeliverUnacknowledgedMessages()

redeliverUnacknowledgedMessages

public void redeliverUnacknowledgedMessages(Set<MessageId> messageIds)

Description copied from class: ConsumerBase

Redelivers the given unacknowledged messages. In Failover mode, the request is ignored if the consumer is not active for the given topic. In Shared mode, the consumers messages to be redelivered are distributed across all the connected consumers. This is a non blocking call and doesn't throw an exception. In case the connection breaks, the messages are redelivered after reconnect.

Specified by:

redeliverUnacknowledgedMessages in class ConsumerBase<T>

          throws PulsarClientException

Throws:

PulsarClientException
