John Vines commented on SHIRO-492:
----------------------------------

Allow a user to request their roles, for starters.

But also for checking large quantities of data for role based access, I need to 
prefetch the set of authorizations to validate with. Currently I'm forcing the 
user to enumerate all known visibilities and checking the system for them one 
by one.

> Subject.getRoles() functionality

> Currently shiro provides the ability to respond whether or not a user has a 
> list of Authorizations. However, while the realms have methods for getting 
> all authorizations (protected), these are not exposed in normal use to allow 
> asking for all Roles. This should be exposed by adding a call to Subject to 
> getRoles, to complement it's existing hasRoles calls. This may require making 
> some of the calls around authorizations, like getAuthorizationInfo in 
> AuthorizingRealm, public.
