Detailed Description

Base class to perform aggregation of two restriction lists.

Aggregation is required if all of the following requirements are met:

1. Partial revocation feature is enabled
2. GRANT/REVOKE operation
3. Either grantor or grantee or both have restrictions associated with them

Task of the aggregator is to evaluate updates required for grantee's restriction. Based on restrictions associated with grantor/grantee: A. Add additional restrictions E.g. - GRANT of a new privileges by a grantor who has restrictions for privileges being granted

• Creation of restrictions through REVOKE B. Remove some restrictions E.g. - GRANT of existing privileges by a grantor without restrictions
• REVOKE of existing privileges
