void	deleteSubscription(String clientId, String subscriberName) Delete a durable subscriber
MessageContainer	getContainer(String physicalName) Allows the lookup of a specific named message container
protected MessageContainerManager	getDelegate()
Map	getDestinations() Returns an unmodifiable map, indexed by String name, of all the Destination objects available in this container
void	poll() Poll for messages
void	redeliverMessage(BrokerClient client, MessageAck ack) Called after a rollback of a JMS transaction to redeliver the message to the consumers dispatch queue
void	removeMessageConsumer(BrokerClient client, ConsumerInfo info)
void	rollbackTransaction(BrokerClient client, String transactionId) A hook when the transaction is about to be rolled back; so discard all outstanding commands that are pending to be written to the Journal

getDestinations

public Map getDestinations()

Description copied from interface: MessageContainerManager

Returns an unmodifiable map, indexed by String name, of all the Destination objects available in this container

Specified by:

getDestinations in interface MessageContainerManager

Returns:

acknowledgeMessage

public void acknowledgeMessage(BrokerClient client,
                               MessageAck ack)
                        throws JMSException

Description copied from interface: MessageContainerManager

Acknowledge a message as being read and consumed by the Consumer

Specified by:

acknowledgeMessage in interface MessageContainerManager

Parameters:

client -

ack -

Throws:

JMSException

acknowledgeTransactedMessage

public void acknowledgeTransactedMessage(BrokerClient client,
                                         String transactionId,
                                         MessageAck ack)
                                  throws JMSException

Description copied from interface: MessageContainerManager

This is a hook to notify the dispatcher for the clients subscription that we have acknowledged a message within a transaction but before the commit - so the message is not really being acknowledged here but this method is intended to be a hook to let the dispatcher know that we can now send another message to the client.

Without this hook, if we have a prefetch value of 1, we can never consume 2 messages in a transaction, since the ack for the first message never arrives until the commit()

Specified by:

acknowledgeTransactedMessage in interface MessageContainerManager

Throws:

JMSException
