JBPermissions

Git Source

Inherits: IJBPermissions

Stores permissions for all addresses and operators. Addresses can give permissions to any other address (i.e. an operator) to execute specific operations on their behalf.

State Variables

WILDCARD_PROJECT_ID

The project ID considered a wildcard, meaning it will grant permissions to all projects.

uint256 public constant override WILDCARD_PROJECT_ID = 0;

permissionsOf

The permissions that an operator has been given by an account for a specific project.

An account can give an operator permissions that only pertain to a specific project ID.

There is no project with a ID of 0 – this ID is a wildcard which gives an operator permissions pertaining to all project IDs on an account's behalf. Use this with caution.

Permissions are stored in a packed uint256. Each of the 256 bits represents the on/off state of a permission. Applications can specify the significance of each permission ID.

mapping(address operator => mapping(address account => mapping(uint256 projectId => uint256))) public override
    permissionsOf;

Functions

hasPermission

Check if an operator has a specific permission for a specific address and project ID.

function hasPermission(
    address operator,
    address account,
    uint256 projectId,
    uint256 permissionId,
    bool includeRoot,
    bool includeWildcardProjectId
)
    public
    view
    override
    returns (bool);

Parameters

Name	Type	Description
operator	address	The operator to check.
account	address	The account being operated on behalf of.
projectId	uint256	The project ID that the operator has permission to operate under. 0 represents all projects.
permissionId	uint256	The permission ID to check for.
includeRoot	bool	A flag indicating if the return value should default to true if the operator has the ROOT permission.
includeWildcardProjectId	bool	A flag indicating if the return value should return true if the operator has the specified permission on the wildcard project ID. true.

Returns

Name	Type	Description
<none>	bool	A flag indicating whether the operator has the specified permission.

hasPermissions

Check if an operator has all of the specified permissions for a specific address and project ID.

function hasPermissions(
    address operator,
    address account,
    uint256 projectId,
    uint256[] calldata permissionIds,
    bool includeRoot,
    bool includeWildcardProjectId
)
    external
    view
    override
    returns (bool);

Parameters

Name	Type	Description
operator	address	The operator to check.
account	address	The account being operated on behalf of.
projectId	uint256	The project ID that the operator has permission to operate under. 0 represents all projects.
permissionIds	uint256[]	An array of permission IDs to check for.
includeRoot	bool	A flag indicating if the return value should default to true if the operator has the ROOT permission.
includeWildcardProjectId	bool	A flag indicating if the return value should return true if the operator has the specified permission on the wildcard project ID.

Returns

Name	Type	Description
<none>	bool	A flag indicating whether the operator has all specified permissions.

_includesPermission

Checks if a permission is included in a packed permissions data.

function _includesPermission(uint256 permissions, uint256 permissionId) internal pure returns (bool);

Parameters

Name	Type	Description
permissions	uint256	The packed permissions to check.
permissionId	uint256	The ID of the permission to check for.

Returns

Name	Type	Description
<none>	bool	A flag indicating whether the permission is included.

_packedPermissions

Converts an array of permission IDs to a packed uint256.

function _packedPermissions(uint8[] calldata permissionIds) internal pure returns (uint256 packed);

Parameters

Name	Type	Description
permissionIds	uint8[]	The IDs of the permissions to pack.

Returns

Name	Type	Description
packed	uint256	The packed value.

setPermissionsFor

Sets permissions for an operator.

Only an address can give permissions to or revoke permissions from its operators.

function setPermissionsFor(address account, JBPermissionsData calldata permissionsData) external override;

Parameters

Name	Type	Description
account	address	The account setting its operators' permissions.
permissionsData	JBPermissionsData	The data which specifies the permissions the operator is being given.

Errors

JBPermissions_PermissionIdOutOfBounds

error JBPermissions_PermissionIdOutOfBounds(uint256 permissionId);

JBPermissions_Unauthorized

error JBPermissions_Unauthorized();
