Extractor class should allow custom extensions
The Extractor class currently only supports FeatureDescriptor s that live in the de.lmu.ifi.dbs.jfeaturelib.features package (or below).
It should support third-party packages, too, as long as they implement the desired interface.
It should also support the output file name "-" to output to stdout. There is a spelling error in the java source:
"cretae the output"
Finding all classes that implement a certain interface is a general problem due to the possibility of having multiple class loaders.
Currently I do not know an easy way to add this functionality in an easy way.
As the Extractor is "just" a convenient tool to simplify the extraction of the features. It will probably not be solved in this place.
I'm thinking about it but will possibly close the issue.
https://code.google.com/p/reflections/ Might be a solution. Nevertheless I still don't like the idea of walking the complete classpath (and loading each and every class)
