Member Function Documentation

◆ aggregate()

void DB_restrictions_aggregator_global_revoke::aggregate ( DB_restrictions & restrictions )

overrideprivatevirtual

If grantee has the restriction list
- Remove only requested restrictions from restriction_list

Parameters

[out] restrictions Fills the parater with the aggregated DB_restrictions

Implements DB_restrictions_aggregator.

Reimplemented in DB_restrictions_aggregator_global_revoke_all.

◆ validate()

Restrictions_aggregator::Status DB_restrictions_aggregator_global_revoke::validate ( )

overrideprivatevirtual

Evaluates the restrictions list of grantor and grantee, as well as requested privilege.

Returns

Status Moves the object in the appropriate status. For instance :

Validated, if validation was performed successfully
NO_op, if there is no aggregation of privileges required.
Error, if an error encountered

Implements DB_restrictions_aggregator.

Reimplemented in DB_restrictions_aggregator_global_revoke_all.

◆ validate_if_grantee_rl_not_empty()

Restrictions_aggregator::Status DB_restrictions_aggregator_global_revoke::validate_if_grantee_rl_not_empty ( )

protected

If grantee restrictions_list is not empty then check the following.

Don't allow revoke if grantor has same restrictions access on a database which is present in grantee's restrictions_list as well.
Check if grantee has same DB level privilege as well as restriction list on the database

Returns

Status Moves the object in the appropriate status. For instance :

Validated, if validation was performed successfully
NO_op, if there is no aggregation of privileges required.
Error, if an error encountered
