How to retrieve right type for system and custom rights

Hi,

I am in the process of retrieving the assigned rights for a folder.

I am able to instantiate the IEffectiveRight object for each defined rights for the folder. I am able to get the right description successfully using getDescription(Locale.US).

When I apply the getRightPluginKind(). I am getting FullClient for first three rights and blank for next three. Since its a system / custom right I am not getting it. How to distinguish it between system and custom right. Is there a way to retrieve the collection and content value as we see in the screen print. Kindly clarify.

Regards,
