org.apache.derby.iapi.sql.dictionary.RoleClosureIterator
Allows iterator over the role grant closure defined by the relation GRANT role-a TO role-b, or its inverse. @see DataDictionary#createRoleClosureIterator @see org.apache.derby.impl.sql.catalog.RoleClosureIteratorImpl

    // If not found in current role, get transitive
    // closure of roles granted to current role and
    // iterate over it to see if permission has
    // been granted to any of the roles the current
    // role inherits.

      permDesc =
        statPerm.getPermissionDescriptor
