ActiveMQ-CPP question

Hi,

I am using ActiveMQ-CPP to consume messages asynchronously.  In my
onMessage() method can I refer to the cms::Message object directly?

All the examples show this being casted to another type (eg.
BytesMessage).  Some messages may not have payloads so I am not
sure what exact type to use for these.

You only need to cast when you want to get to the Message body,
otherwise you can safely access the Message properties from the passed
in cms::Message pointer.
