Should the public constructor for TrainingParameters be made private?

[kottmann]

We probably set default somewhere in case they are missing. This change here would set the defaults to the default training parameters.

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.

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.

[smarthi]

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

[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?
