No, please don’t make the constructor private. opennlp-tools is used as a library also. If you make the TrainingParameters constructor private, you can ONLY create training parameters via a file. Also a defaultTrainingParameters method uses this constructor.

Should the public constructor for TrainingParameters be made private?

Thanks, @danielruss. Maybe a javadoc comment on the TrainingParameters constructor that says you can use ModelUtil.createDefaultTrainingParameters() would be helpful in case someone doesn't know it exists.

Folks could we merge this into master after fixing the javadocs @kojisekig

Thanks everyone for reviewing this!

As @jzonthemtn commented, when I created this patch, I thought we could add the notice in the javadoc of TrainingParameters constructor so that users can know the existence of ModelUtil.createDefaultTrainingParameters(), but I noticed that the javadoc of ModelUtil.createDefaultTrainingParameters() says

Note: Do not use this method, internal use only!

So I didn't touch them. :)

Can someone explain the background on this?
