function __ERC20VotesLegacyMock_init() internal onlyInitializing;

__ERC20VotesLegacyMock_init_unchained

function __ERC20VotesLegacyMock_init_unchained() internal onlyInitializing;

checkpoints

Get the pos-th checkpoint for account.

function checkpoints(address account, uint32 pos) public view virtual returns (Checkpoint memory);

numCheckpoints

Get number of checkpoints for account.

function numCheckpoints(address account) public view virtual returns (uint32);

delegates

Get the address account is currently delegating to.

function delegates(address account) public view virtual returns (address);

getVotes

Gets the current votes balance for account

function getVotes(address account) public view virtual returns (uint256);

getPastVotes

*Retrieve the number of votes for account at the end of blockNumber. Requirements:

• blockNumber must have been already mined*

function getPastVotes(address account, uint256 blockNumber) public view virtual returns (uint256);

getPastTotalSupply

*Retrieve the totalSupply at the end of blockNumber. Note, this value is the sum of all balances. It is NOT the sum of all the delegated votes! Requirements:

• blockNumber must have been already mined*

function getPastTotalSupply(uint256 blockNumber) public view virtual returns (uint256);

_checkpointsLookup

Lookup a value in a list of (sorted) checkpoints.

function _checkpointsLookup(Checkpoint[] storage ckpts, uint256 blockNumber) private view returns (uint256);

delegate

Delegate votes from the sender to delegatee.

function delegate(address delegatee) public virtual;

delegateBySig

Delegates votes from signer to delegatee

function delegateBySig(address delegatee, uint256 nonce, uint256 expiry, uint8 v, bytes32 r, bytes32 s)
    public
    virtual;

_maxSupply

Maximum token supply. Defaults to type(uint224).max (2^224^ - 1).

function _maxSupply() internal view virtual returns (uint224);

_update

Move voting power when tokens are transferred. Emits a IVotes-DelegateVotesChanged event.

function _update(address from, address to, uint256 amount) internal virtual override;

_delegate

Change delegation for delegator to delegatee. Emits events IVotes-DelegateChanged and {IVotes-DelegateVotesChanged}.

function _delegate(address delegator, address delegatee) internal virtual;

_moveVotingPower

function _moveVotingPower(address src, address dst, uint256 amount) private;

_writeCheckpoint

function _writeCheckpoint(
    Checkpoint[] storage ckpts,
    function(uint256, uint256) view returns (uint256) op,
    uint256 delta
) private returns (uint256 oldWeight, uint256 newWeight);

_add

function _add(uint256 a, uint256 b) private pure returns (uint256);

_subtract

function _subtract(uint256 a, uint256 b) private pure returns (uint256);

_unsafeAccess

Access an element of the array without performing bounds check. The position is assumed to be within bounds.

function _unsafeAccess(Checkpoint[] storage ckpts, uint256 pos) private pure returns (Checkpoint storage result);

Structs

struct Checkpoint {
    uint32 fromBlock;
