/** | |
* @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(); | |
