Method Detail

setConsumerTag

public void setConsumerTag(int consumerTag)

Overrides:

getConsumerTagString

public String getConsumerTagString()

notifyMessage

public void notifyMessage(AbstractJMSMessage jmsMessage)

This is invoked by the session thread when emptying the session message queue. We first check if the message is valid (match the selector) and then deliver it to the message listener or to the sync consumer queue.

Overrides:

notifyMessage in class BasicMessageConsumer<UnprocessedMessage_0_10>

Parameters:

jmsMessage - this message has already been processed so can't redo preDeliver

preDeliver

protected void preDeliver(AbstractJMSMessage jmsMsg)

Overrides:

preDeliver in class BasicMessageConsumer<UnprocessedMessage_0_10>

createJMSMessageFromUnprocessedMessage
