Addresses can give permissions to any other address to take specific actions throughout the Juicebox ecosystem on their behalf. These addresses are called operators.

Permissions are stored as a uint256, with each boolean bit representing whether or not an oporator has the permission identified by that bit's index in the 256 bit uint256. Indexes must be between 0 and 255. The directory of permissions, along with how they uniquely mapp to indexes, are managed externally. This contract doesn't know or care about specific permissions and their indexes.

State Variables

permissionsOf

The permissions that an operator has to operate on a specific domain.

An account can give an operator permissions that only pertain to a specific domain. There is no domain with an ID of 0 -- accounts can use the 0 domain to give an operator permissions to operator on their personal behalf.

mapping(address => mapping(address => mapping(uint256 => uint256))) public override permissionsOf;

Functions

hasPermission

Whether or not an operator has the permission to take a certain action pertaining to the specified domain.

function hasPermission(address _operator, address _account, uint256 _domain, uint256 _permissionIndex)
    external
    view
    override
    returns (bool);

Parameters

Name	Type	Description
_operator	address	The operator to check.
_account	address	The account that has given out permission to the operator.
_domain	uint256	The domain that the operator has been given permissions to operate.
_permissionIndex	uint256	the permission to check for.

Returns

Name	Type	Description
<none>	bool	Whether the operator has the specified permission.

hasPermissions

Whether or not an operator has the permission to take certain actions pertaining to the specified domain.

function hasPermissions(address _operator, address _account, uint256 _domain, uint256[] calldata _permissionIndexes)
    external
    view
    override
    returns (bool);

Parameters

Name	Type	Description
_operator	address	The operator to check.
_account	address	The account that has given out permissions to the operator.
_domain	uint256	The domain that the operator has been given permissions to operate.
_permissionIndexes	uint256[]	An array of permission indexes to check for.

Returns

Name	Type	Description
<none>	bool	Whether the operator has all specified permissions.

setOperator

Sets permissions for an operator.

function setOperator(address _operator, uint256 _domain, uint256[] calldata _permissionIndexes) external override;

Parameters

Name	Type	Description
_operator	address	The operator to give permission to.
_domain	uint256	The domain that the operator is being given permissions to operate.
_permissionIndexes	uint256[]	An array of indexes of permissions to set.

setOperators

Sets permissions for many operators.

function setOperators(
    address[] calldata _operators,
    uint256[] calldata _domains,
    uint256[][] calldata _permissionIndexes
) external override;

Parameters

Name	Type	Description
_operators	address[]	The operators to give permission to.
_domains	uint256[]	The domains that can be operated. Set to 0 to allow operation of account level actions.
_permissionIndexes	uint256[][]	The level of power each operator should have.

_packedPermissions

Converts an array of permission indexes to a packed int.

function _packedPermissions(uint256[] calldata _indexes) private pure returns (uint256 packed);

Parameters

Name	Type	Description
_indexes	uint256[]	The indexes of the permissions to pack.

Returns

Name	Type	Description
packed	uint256	The packed result.
