public UserMapping asUserMapping() {
        return user_mapping;
    }
Returns a user mapping containing all authorizations and configurations
parsed so far. This user mapping will be backed by the data being parsed,
thus any additional authorizations or configurations will be available
in the object returned by this function even after this function has
returned, once the data corresponding to those authorizations or
configurations has been parsed.

@return A user mapping containing all authorizations and configurations
