Inherits: IEnabler

Abstract contract that implements the IEnabler interface

This contract is designed to be used as a base contract for periphery contracts that need to be enabled and disabled. It additionally is not opionated about whether a caller is permitted to enable/disable the contract, and delegates it to a virtual function. It is a periphery contract, as it does not require any privileged access to the Olympus protocol.

State Variables

isEnabled

Whether the contract is enabled

bool public isEnabled;

Functions

onlyEnabled

modifier onlyEnabled();

onlyDisabled

modifier onlyDisabled();

_onlyOwner

Implementation-specific validation of ownership

Implementing contracts should override this function to perform the appropriate validation and revert if the caller is not permitted to enable/disable the contract.

function _onlyOwner() internal view virtual;

_enable

Implementation-specific enable function

*This function is called by the enable() function The implementing contract can override this function and perform the following:

1. Validate any parameters (if needed) or revert
2. Validate state (if needed) or revert
3. Perform any necessary actions, apart from modifying the isEnabled state variable*

function _enable(bytes calldata enableData_) internal virtual;

Parameters

Name	Type	Description
enableData_	bytes	Custom data that can be used by the implementation. The format of this data is left to the discretion of the implementation.

enable

Enables the contract

Implementing contracts should implement permissioning logic

function enable(bytes calldata enableData_) external onlyDisabled;

Parameters

Name	Type	Description
enableData_	bytes	Optional data to pass to a custom enable function

_disable

Implementation-specific disable function

*This function is called by the disable() function The implementing contract can override this function and perform the following:

1. Validate any parameters (if needed) or revert
2. Validate state (if needed) or revert
3. Perform any necessary actions, apart from modifying the isEnabled state variable*

function _disable(bytes calldata disableData_) internal virtual;

Parameters

Name	Type	Description
disableData_	bytes	Custom data that can be used by the implementation. The format of this data is left to the discretion of the implementation.

disable

Disables the contract

Implementing contracts should implement permissioning logic

function disable(bytes calldata disableData_) external onlyEnabled;

Parameters

Name	Type	Description
disableData_	bytes	Optional data to pass to a custom disable function

supportsInterface

function supportsInterface(bytes4 interfaceId) public view virtual returns (bool);
