function eip712Domain() public view virtual returns (bytes1 fields, string name, string version, uint256 chainId, address verifyingContract, bytes32 salt, uint256[] extensions)_See {EIP-5267}.
Available since v4.9._

event Initialized(uint8 version)Triggered when the contract has been initialized or reinitialized.
Inherited from UUPSUpgradeable
proxiableUUID
function proxiableUUID() external view virtual returns (bytes32)_Implementation of the ERC1822 {proxiableUUID} function. This returns the storage slot used by the implementation. It is used to validate the implementation's compatibility when performing an upgrade.
IMPORTANT: A proxy pointing at a proxiable contract should not be considered proxiable itself, because this risks bricking a proxy that upgrades to it, by delegating to itself until out of gas. Thus it is critical that this function revert if invoked through a proxy. This is guaranteed by the notDelegated modifier._
upgradeTo
function upgradeTo(address newImplementation) public virtual_Upgrade the implementation of the proxy to newImplementation.
Calls {_authorizeUpgrade}.
Emits an {Upgraded} event._
upgradeToAndCall
function upgradeToAndCall(address newImplementation, bytes data) public payable virtual_Upgrade the implementation of the proxy to newImplementation, and subsequently execute the function call encoded in data.
Calls {_authorizeUpgrade}.
Emits an {Upgraded} event._
Inherited from ERC1967Upgrade
Inherited from IERC1967
Upgraded
event Upgraded(address implementation)Emitted when the implementation is upgraded.
AdminChanged
event AdminChanged(address previousAdmin, address newAdmin)Emitted when the admin account has changed.
BeaconUpgraded
event BeaconUpgraded(address beacon)Emitted when the beacon is changed.
