Hi all,

I am trying to find out the type of data that will result from
applying a SLD with a rendering transformation. The
getTransformation() method in the FeatureTypeStyle class gives me an
Expression object, and (as far as I have seen, correct me if I am
wrong) this is a always a ProcessFunction in the case of a rendering
trasformation.

Getting the process name and asking the corresponding
ProcessFunctionFactory about its outputs should be enough for what I
want to do, but the ProcessFunction class is package local and it does
not expose the information about the underlying process.

Any suggestions about how to do this?

Thanks in advance
