⛔AAccessControlled

AAccessControlled

This abstract contract outlines basic functionality, declares functions that need to be implemented to provide a deterministic connection to ZNSAccessController module.

In order to connect an arbitrary module to ZNSAccessController and it's functionality, this contract needs to be inherited by the module.

AccessControllerSet

event AccessControllerSet(address accessController)

Emitted when the access controller contract address is set.

WrongAccessControllerAddress

error WrongAccessControllerAddress(address accessController)

Reverts when the access controller is set to an incorrect address.

Parameters

Name	Type	Description
accessController	address	The address that was attempted to be set as the access controller.

accessController

contract IZNSAccessController accessController

Address of the ZNSAccessController contract.

onlyAdmin

modifier onlyAdmin()

Modifier to make a function callable only when caller is an admin. Implemented here to avoid declaring this in every single contract that uses it.

onlyRegistrar

modifier onlyRegistrar()

Revert if msg.sender is not the ZNSRootRegistrar.sol contract or an address holding REGISTRAR_ROLE.

getAccessController

function getAccessController() external view returns (address)

Universal getter for accessController address on any contract that inherits from AAccessControlled.

setAccessController

function setAccessController(address accessController_) external

Universal setter for accessController address on any contract that inherits from AAccessControlled. Only ADMIN can call this function. Fires AccessControllerSet event.

Parameters

Name	Type	Description
accessController_	address	The address of the new access controller

_setAccessController

function _setAccessController(address _accessController) internal

Internal function to set the access controller address.

This function checks if the caller has the admin role in the current in-state contract and checks if the new access controller address passed is in fact a ZNSAccessController contract that is already set up with the same caller as an admin. This prevents from setting the wrong address.

Parameters

Name	Type	Description
_accessController	address	Address of the ZNSAccessController contract.
