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]restrictionsFills 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
