I thought it did, but looking at the DescribeProcess schema I see at
least one output is required. And at least one input as well.
Neither of them is actually a requirement in Java, and not a requirement
in our process API either (a process could be a source of some kind with
all the params built-in, think a random number generator, it is not
required to have an input, thought you may make up some with a seed and
a distribution kind).
I'd leave it be for the moment. In order for the processes to work in
the GeoServer WPS one needs to satisfy a series of requirements, like
using only certain data types. I guess having at least one input and
one output will add to that list (which sooner or later I'll have to
write down somewhere).

Cool. Any preference for a package?
Also, shall we get rid of DEMTools, since it does nothing?

Ok. Another thing that I'd like to see is a similar factory that allows
the processes to be classes instead of static methods. Something like:
@DescribeProcess(...)
public class MyProcess {
public MyProcess() {};
@DescribeResult(....)
public <resultType> execute(@DescribeParam(...) String p1,
@DescribeParam(...) int p2,
...) throws Exception {
...
}
}
And then I guess the factory would take a list of classes with the
above annotations. A possible variant would be something that takes
parameters as bean properties and has a execute method that takes
no extra params (besides and eventual progress listener).
Cheers
Andrea
