Re: [Java-ML-support] instance key, how to set?

[Thomas A. <th...@ab...>]

Have you tried the documentation on java-ml.sf.net?

At the moment there is no way to use keys with instances, everything is 
index based.

If you think the javadocs need to be expanded, we would be very grateful 
if you can expand them and submit the patches and I'll be happy to apply 
them to the code-base.


cheers,
Thomas
