Solidity API

_This module provides a number of utility functions and modifiers for interacting with the Spanning Network.

It includes:

• Functions abstracting delegate state and methods
• Functions for multi-domain ownership

Note: This module is meant to be used through inheritance._

address delegateLegacyAddress

contract ISpanningDelegate delegate_

bytes32 rootOwner

function __Spanning_init(address delegate) internal

_Initializes a Spanning base module.

Note: The initial rootOwner is set to whomever deployed the contract._

function __Spanning_init_unchained(address delegate) internal

function isSpanning() external pure returns (bool)

modifier onlySpanning()

Reverts if the function is executed by anyone but the Delegate.

function isSpanningCall() public view returns (bool)

function getDomain() internal view returns (bytes4)

function delegateAddress() internal view returns (address)

function updateDelegate(address newDelegateLegacyAddress) external

Updates Delegate's legacy (local) address.

function makeRequest(bytes32 programAddress, bytes payload) internal virtual

_Creates a function request for a delegate to execute.

Note: This can result in either a local or cross-domain transaction._

function getLegacyFromAddress(bytes32 inputAddress) internal view returns (address)

_Gets a Legacy Address from an Address, if in the same domain.

Note: This function can be used to create backwards-compatible events._

function getDomainFromAddress(bytes32 inputAddress) internal pure returns (bytes4)

Gets a Domain from an Address

function getAddressFromLegacy(address legacyAddress) internal view returns (bytes32)

Creates an Address from a Legacy Address, using the local domain.

function spanningMsgSender() internal view returns (bytes32)

function spanningTxnSender() internal view returns (bytes32)

function isValidSpanningInfo() internal view returns (bool)

function spanningMsgSenderUnchecked() internal view returns (bytes32)

function spanningTxnSenderUnchecked() internal view returns (bytes32)

modifier onlyOwner()

Reverts if the function is executed by anyone but the owner.

function owner() public view virtual returns (bytes32)

function renounceOwnership() public virtual

_Sets the owner to null, effectively removing contract ownership.

Note: It will not be possible to call onlyOwner functions anymore Note: Can only be called by the current owner_

function transferOwnership(bytes32 newOwnerAddress) public virtual

_Assigns new owner for the contract.

Note: Can only be called by the current owner_

function _transferOwnership(bytes32 newOwnerAddress) internal virtual

Transfers ownership of the contract to a new Address.

uint256[46] __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.
