Detailed Description

Factory class that solely creates an object of type Restrictions_aggregator.

  • The concrete implemenations of Restrictions_aggregator cannot be created directly since their constructors are private. This class is declared as friend in those concrete implementations.
  • It also records the CURRENT_USER in the binlog so that partial_revokes can be executed on slave with context of current user

)
static

A factory method that creates objects from Restrictions_aggregator hierarchy.

Creates an object iif –partial_revokes system variable is ON. It also records the CURRENT_USER in the binlog so that partial_revokes can be executed on slave with context of current user

Parameters
[in,out]thdThread handle
[in]acl_userGrantee's info from ACL Cache
[in]dbDatabase name if it is DB level operation
[in]rightsaccess specified in the SQL statement
[in]is_grant_revoke_all_on_dbflag that indicates if the REVOKE/GRANT ALL was executed on a DB
Returns
A restriction aggregator object
Return values
nullptrif partial_revokes system variable is OFF
