ERC165Upgradeable
Implementation of the {IERC165} interface. Contracts that want to implement ERC165 should inherit from this contract and override {supportsInterface} to check for the additional interface id that will be supported. For example: solidity function supportsInterface(bytes4 interfaceId) public view virtual override returns (bool) { return interfaceId == type(MyInterface).interfaceId || super.supportsInterface(interfaceId); } Alternatively, {ERC165Storage} provides an easier to use but more expensive implementation.
