Disableable

Inherits: IDisableable, Authorizable

This abstract contract provides the ability to disable the inheriting contract, triggering (if implemented) an on-disable routine hook.

This contract also implements whenEnabled and whenDisabled modifiers to restrict the methods that can be called on each state.

bool public contractEnabled = true;

External method to trigger the contract disablement

This method is virtual and should be overriden to implement

Internal virtual view to check if the contract is enabled

This method is virtual and could be overriden for non-standard implementations

function _isEnabled() internal view virtual returns (bool _enabled);
