ConsumerEvent
public ConsumerEvent(ConsumerEventSource source,
javax.jms.Destination destination,
ConsumerId consumerId,
int consumerCount)
getAdvisor
public ConsumerEventSource getAdvisor()
getDestination
public javax.jms.Destination getDestination()
getConsumerCount
public int getConsumerCount()
- Returns the current number of consumers active at the time this advisory was sent.
Note that this is not the number of consumers active when the consumer started consuming.
It is usually more vital to know how many consumers there are now - rather than historically
how many there were when a consumer started. So if you create a
ConsumerListener
after many consumers have started, you will receive a ConsumerEvent for each consumer. However the
getConsumerCount()
method will always return the current active consumer count on each event.
getConsumerId
public ConsumerId getConsumerId()
isStarted
public abstract boolean isStarted()
