CompositeData has no keys() method?

Question

I'm using JMX to save some diagnostic information from a remote process. Looking at the interface in jconsole shows that the return type is CompositeData (the data actually comes back as CompositeDataSupport). I want to output all the key/value pairs that are associated with this object.

The problem is that the interface just seems to have a "values()" method with no way of getting the keys. Am I missing something here? Is there some other way to approach this task?

Thanks!

If I'm not mistaken you could do

Set< String > keys = cData.getCompositeType().keySet();

(given that cData is a CompositeData object)
