setOperator

Contract: JBOperatorStore​‌

Interface: IJBOperatorStore

Step by step

Sets permissions for an operator.

Only an address can set its own operators.

Definition

 function setOperator(JBOperatorData calldata _operatorData) external override { ... }

• _operatorData is the JBOperatorData that specifies the params for the operator being set.
• The function can be accessed externally by anyone.
• The function overrides a function definition from the IJBOperatorStore interface.
• The function doesn't return anything.

Body

1. Pack the provided permissions into a uint256. Each bit of the resulting value represents whether or not permission has been granted for that index.

   // Pack the indexes into a uint256.
   uint256 _packed = _packedPermissions(_operatorData.permissionIndexes);

   Internal references:

   • _packedPermissions

2. Store the packed permissions as the permissions of the provided operator, on behalf of the msg.sender, specifically for the provided domain.

   // Store the new value.
   permissionsOf[_operatorData.operator][msg.sender][_operatorData.domain] = _packed;

   Internal references:

   • permissionsOf

3. Emit a SetOperator event with the relevant parameters.

   emit SetOperator(
     _operatorData.operator,
     msg.sender,
     _operatorData.domain,
     _operatorData.permissionIndexes,
     _packed
   );

   Event references:

   • SetOperator
