function __SpanningERC20Container_init(string nameIn, string symbolIn, address delegate) internal

Creates the instance and assigns required values.

function __SpanningERC20Container_init_unchained(string nameIn, string symbolIn, address delegate) internal

function name() public view virtual returns (string)

function symbol() public view virtual returns (string)

function decimals() public view virtual returns (uint8)

Returns the number of decimals used to get its user representation. For example, if decimals equals 2, a balance of 505 tokens should be displayed to a user as 5.05 (505 / 10 ** 2).

function totalSupply() public view virtual returns (uint256)

function balanceOf(address accountLegacyAddress) public view virtual returns (uint256)

Returns the amount of tokens owned by an account.

function balanceOf(bytes32 account) public view virtual returns (uint256)

Returns the amount of tokens owned by an account.

function transfer(address receiverLegacyAddress, uint256 amount) public virtual returns (bool)

Moves tokens from the caller's account to another account.

function transfer(bytes32 receiverAddress, uint256 amount) public virtual returns (bool)

Moves tokens from the caller's account to another account.

function allowance(address senderLegacyAddress, address receiverLegacyAddress) public view virtual returns (uint256)

_Gets the number of authorized tokens in the allowance pair.

Note: This value can change when {approve} or {transferFrom} are called Note: The result is zero when an entry does not exist in the map_

function allowance(bytes32 senderAddress, bytes32 receiverAddress) public view virtual returns (uint256)

_Gets the number of authorized tokens in the allowance pair.

function approve(address receiverLegacyAddress, uint256 amount) public virtual returns (bool)

_Sets an allowance for a pair of addresses (sender and receiver).

Note: There can be race conditions due to ordering. See more: https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729_

function approve(bytes32 receiverAddress, uint256 amount) public virtual returns (bool)

_Sets an allowance for a pair of addresses (sender and receiver).

function transferFrom(address senderLegacyAddress, address receiverLegacyAddress, uint256 amount) public virtual returns (bool)

_Transfers tokens from from sender to receiver.

Note: This uses the allowance mechanism to transfer tokens._

function transferFrom(bytes32 senderAddress, bytes32 receiverAddress, uint256 amount) public virtual returns (bool)

_Transfers tokens from from sender to receiver.

Note: This uses the allowance mechanism to transfer tokens._

function updateRecords() public virtual returns (bool)

_Pulls read-only information relevant to the domain ownership from the appropriate middleware node or domain

Note: This function should be called prior to reading any information through this domain, to ensure data is up to date_

function increaseAllowance(address receiverLegacyAddress, uint256 addedValue) public virtual returns (bool)

_Atomically increases the allowance

This is an alternative to {approve} that can be used as a mitigation for problems described in {ISpanningERC20-approve}._

function increaseAllowance(bytes32 receiverAddress, uint256 addedValue) public virtual returns (bool)

_Atomically increases the allowance

This is an alternative to {approve} that can be used as a mitigation for problems described in {ISpanningERC20-approve}._

function decreaseAllowance(address receiverLegacyAddress, uint256 subtractedValue) public virtual returns (bool)

_Atomically decreases the allowance

This is an alternative to {approve} that can be used as a mitigation for problems described in {ISpanningERC20-approve}._

function decreaseAllowance(bytes32 receiverAddress, uint256 subtractedValue) public virtual returns (bool)

_Atomically decreases the allowance

This is an alternative to {approve} that can be used as a mitigation for problems described in {ISpanningERC20-approve}._

function _transfer(bytes32 senderAddress, bytes32 receiverAddress, uint256 amount) internal virtual

function _spendAllowance(bytes32 senderAddress, bytes32 receiverAddress, uint256 amount) internal virtual

_Updates senderAddress s allowance for spender based on spent amount.

Does not update the allowance amount in case of infinite allowance. Revert if not enough allowance is available.

Might emit an {Approval} event._

function _beforeTokenTransfer(bytes32 senderAddress, bytes32 receiverAddress, uint256 amount) internal virtual

Hook that is called before any transfer of tokens.

function _duringTokenTransfer(bytes32 senderAddress, bytes32 receiverAddress, uint256 amount) internal virtual

uint256[45] __gap

This empty reserved space is put in place to allow future versions to add new variables without shifting down storage in the inheritance chain. See https://docs.openzeppelin.com/contracts/4.x/upgradeable#storage_gaps We use a standard of 50 storage slots. The amount referenced below is based on: 50 - numberOfClassMemberVariables.
