How to get all allowed permissions on a single role of a project area from Rtc Using REST call or client plain java Libraries?

Hi TechLeads,
I want all the allowed permissions for each individual role for one Project area from Rtc. As I know how to get Roles in the form of XML data using REST call(or by using client plain java libraries),Is there any API to get the all permissions for each & every individual role for one particular project area?
Thank you
