On page
http://activemq.apache.org/advisory-message.html
data structures named ProducerInfo + ConsumerInfo are mentioned.
Where do I find these data structures explained (resp. which fields they
contain in detail) ?
Furthermore I wonder how I can detect wether an incoming msg on an Advisorc
topic is a ProducerInfo OR ConsumerInfo type msg? On the web page above a
java sample is shown where an incoming msg is always casted on ProducerInfo:
ProducerInfo prod = (ProducerInfo) aMsg.getDataStructure();
Why ProducerInfo and not ConsumerInfo?
I expected some sort of investigation first:
if (aMsg instanceOf ProducerInfo) {
ProducerInfo prod = (ProducerInfo) aMsg.getDataStructure(); }
else {
ConsumerInfo prod = (ConsumerInfo) aMsg.getDataStructure(); }
....
So how should this look like officially? Is there a more elaborated java
example?
Ben
