// SPDX-License-Identifier: MIT // OpenZeppelin Contracts (last updated v4.7.0) (proxy/utils/Initializable.sol) pragma solidity ^0.8.2; import "../../utils/AddressUpgradeable.sol"; /** * @dev This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed * behind a proxy. Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect. * * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be * reused. This mechanism prevents re-execution of each "step" but allows the creation of new initialization steps in * case an upgrade adds a module that needs to be initialized. * * For example: * * [.hljs-theme-light.nopadding] * ``` * contract MyToken is ERC20Upgradeable { * function initialize() initializer public { * __ERC20_init("MyToken", "MTK"); * } * } * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable { * function initializeV2() reinitializer(2) public { * __ERC20Permit_init("MyToken"); * } * } * ``` * * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}. * * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity. * * [CAUTION] * ==== * Avoid leaving a contract uninitialized. * * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation * contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke * the {_disableInitializers} function in the constructor to automatically lock it when it is deployed: * * [.hljs-theme-light.nopadding] * ``` * /// @custom:oz-upgrades-unsafe-allow constructor * constructor() { * _disableInitializers(); * } * ``` * ==== */ abstract contract Initializable { /** * @dev Indicates that the contract has been initialized. * @custom:oz-retyped-from bool */ uint8 private _initialized; /** * @dev Indicates that the contract is in the process of being initialized. */ bool private _initializing; /** * @dev Triggered when the contract has been initialized or reinitialized. */ event Initialized(uint8 version); /** * @dev A modifier that defines a protected initializer function that can be invoked at most once.
