Examples of org.activemq.advisories.ProducerDemandAdvisor

org.activemq.advisories.ProducerDemandAdvisor
A ProducerDemandAdvisor is used to know when a destination is in demand. Sometimes generating messages to send to a destination is very expensive and the application would like to avoid producing messages if there are no active consumers for the destination. There is a "demand" for messages when a consumer does come active. This object uses Advisory messages to know when consumer go active and inactive.
