IDiamondCut

Interface for upgrading the Diamond proxy's Business Logic Resolver (BLR), configuration identifier, and version in a single or multi-step operation.

Methods

getConfigInfo

function getConfigInfo() external view returns (address resolver_, bytes8 proxyVersion_, bytes32 configurationId_, uint256 configurationVersion_, bool replacementEnabled_)

Returns the active resolver address, configuration identifier, and version.

Returns

Name	Type	Description
resolver_	address	Address of the current Business Logic Resolver.
proxyVersion_	bytes8	proxy version.
configurationId_	bytes32	Identifier of the active configuration.
configurationVersion_	uint256	Version number of the active configuration.
replacementEnabled_	bool	Whether replacement is enabled.

getStaticFunctionSelectors

function getStaticFunctionSelectors() external pure returns (bytes4[] staticFunctionSelectors_)

Gets all function selectors of a facet

Returns

Name	Type	Description
staticFunctionSelectors_	bytes4[]	Face functions selectors

getStaticInterfaceIds

function getStaticInterfaceIds() external pure returns (bytes4[] staticInterfaceIds_)

Gets all interfaces ids of a facet.

Returns

Name	Type	Description
staticInterfaceIds_	bytes4[]	Face interface ids

getStaticResolverKey

function getStaticResolverKey() external pure returns (bytes32 staticResolverKey_)

Gets the static resolver key

Returns

Name	Type	Description
staticResolverKey_	bytes32	Static resolver key

updateConfig

function updateConfig(bytes32 _newConfigurationId, uint256 _newVersion) external nonpayable

For the current BLR, update its configuration identifier and version.

Parameters

Name	Type	Description
_newConfigurationId	bytes32	The new configuration identifier to apply.
_newVersion	uint256	The version number associated with the new configuration.

updateConfigVersion

function updateConfigVersion(uint256 _newVersion) external nonpayable

For the current BLR and configuration, update the used version.

Parameters

Name	Type	Description
_newVersion	uint256	The new version number to set for the current configuration.

updateReplacementEnabled

function updateReplacementEnabled(bool _newReplacementEnabled) external nonpayable

For the current BLR update its configuration

Parameters

Name	Type	Description
_newReplacementEnabled	bool	The replacement enabled flag to set*

updateResolver

function updateResolver(contract IBusinessLogicResolver _newResolver, bytes32 _newConfigurationId, uint256 _newVersion, bool _newReplacementEnabled) external nonpayable

Replaces the Business Logic Resolver with a new one, setting configuration and version.

Parameters

Name	Type	Description
_newResolver	contract IBusinessLogicResolver	The new BLR contract address to wire into the proxy.
_newConfigurationId	bytes32	The configuration identifier to activate on the new resolver.
_newVersion	uint256	The version number associated with the new configuration.
_newReplacementEnabled	bool	The replacement enabled flag to set.

Events

ConfigUpdated

event ConfigUpdated(address indexed caller, bytes32 oldConfigurationId, bytes32 newConfigurationId, uint256 oldConfigurationVersion, uint256 newConfigurationVersion)

Emitted when the active configuration identifier is replaced.

updateConfig() combines an id change and a version change in one call; both get a complete old/new pair here.

Parameters

Name	Type	Description
caller indexed	address	Account that performed the update.
oldConfigurationId	bytes32	Previous configuration identifier.
newConfigurationId	bytes32	New configuration identifier.
oldConfigurationVersion	uint256	Previous configuration version.
newConfigurationVersion	uint256	Version activated for the new configuration.

ConfigVersionUpdated

event ConfigVersionUpdated(address indexed caller, uint256 oldConfigurationVersion, uint256 newConfigurationVersion)

Emitted when the pinned version of the active configuration is replaced.

Parameters

Name	Type	Description
caller indexed	address	Account that performed the update.
oldConfigurationVersion	uint256	Previous configuration version.
newConfigurationVersion	uint256	New configuration version.

ReplacementEnabledUpdated

event ReplacementEnabledUpdated(address indexed caller, bool oldReplacementEnabled, bool newReplacementEnabled)

Emitted when the replacement-enabled flag is replaced.

Parameters

Name	Type	Description
caller indexed	address	Account that performed the update.
oldReplacementEnabled	bool	Previous replacement-enabled flag.
newReplacementEnabled	bool	New replacement-enabled flag.

ResolverUpdated

event ResolverUpdated(address indexed caller, address oldResolver, address newResolver, bytes32 oldConfigurationId, bytes32 newConfigurationId, uint256 oldConfigurationVersion, uint256 newConfigurationVersion, bool oldReplacementEnabled, bool newReplacementEnabled)

Emitted when the resolver-proxy's Business Logic Resolver is replaced.

updateResolver() combines four changes in one call; every one of them gets a complete old/new pair here rather than only the fields that happen to differ.

Parameters

Name	Type	Description
caller indexed	address	Account that performed the update.
oldResolver	address	Previous Business Logic Resolver address.
newResolver	address	New Business Logic Resolver address.
oldConfigurationId	bytes32	Previous configuration identifier.
newConfigurationId	bytes32	Configuration identifier activated on the new resolver.
oldConfigurationVersion	uint256	Previous configuration version.
newConfigurationVersion	uint256	Configuration version activated on the new resolver.
oldReplacementEnabled	bool	Previous replacement-enabled flag.
newReplacementEnabled	bool	Replacement-enabled flag activated on the new resolver.

Errors

InvalidBusinessLogicResolver

error InvalidBusinessLogicResolver(address invalidResolver)

Thrown when a candidate resolver is the zero address or fails the isBusinessLogicResolver() identity check.

Parameters

Name	Type	Description
invalidResolver	address	The address that failed validation.
