RoleGrantDescriptor (Apache Derby V10.14 Internals)

java.lang.Object
- org.apache.derby.iapi.sql.dictionary.TupleDescriptor
- - org.apache.derby.iapi.sql.dictionary.RoleGrantDescriptor

All Implemented Interfaces:

Dependable, Provider
```
public class RoleGrantDescriptor
extends TupleDescriptor
implements Provider
```
This class is used by rows in the SYS.SYSROLES system table. An instance contains information for exactly: One <role definition>, cf. ISO/IEC 9075-2:2003 section 12.4 or one <grant role statement>, section 12.5. A role definition is also modeled as a role grant (hence the class name), but with the special grantor "_SYSTEM", and with a grantee of the definer, in Derby this is always the current user. For a role definition, the WITH ADMIN flag is also set. The information contained in the isDef flag is usually redundant, but was added as a precaution against a real user named _SYSTEM, for example when upgrading an older database that did not forbid this.
