KpisFacet

Diamond facet that exposes KPI data management to the proxy.

Selectors exposed: - initializeKpis - addKpiData - getLatestKpiData - getMinDate - isCheckPointDate

Methods

addKpiData

function addKpiData(uint256 _date, uint256 _value, address _project) external nonpayable

Records a KPI data point for _project at _date.

Persists a KPI checkpoint for _project; reverts unless _date is valid. Emits {KpiDataAdded}.

Parameters

Name	Type	Description
_date	uint256	Unix timestamp for the data point.
_value	uint256	KPI value to record.
_project	address	Address of the project the data point belongs to.

getLatestKpiData

function getLatestKpiData(uint256 _from, uint256 _to, address _project) external view returns (uint256 value_, bool exists_)

Returns the most recent KPI value for _project within [_from, _to].

Reverts with InvalidDateRange if _from > _to.

Parameters

Name	Type	Description
_from	uint256	Start of the search window (Unix timestamp, inclusive).
_to	uint256	End of the search window (Unix timestamp, inclusive).
_project	address	Address of the project to query.

Returns

Name	Type	Description
value_	uint256	The latest KPI value found in the range, or 0 if none.
exists_	bool	true if at least one data point exists within the range.

getMinDate

function getMinDate() external view returns (uint256 minDate_)

Returns the earliest valid date for KPI data points on this token.

Returns

Name	Type	Description
minDate_	uint256	The configured minimum date (Unix timestamp).

getStaticFunctionSelectors

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

Gets all function selectors of a facet

Returns

Name	Type	Description
_0	bytes4[]	Face functions selectors

getStaticInterfaceIds

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

Gets all interfaces ids of a facet.

Returns

Name	Type	Description
_0	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

initializeKpis

function initializeKpis() external nonpayable

Initialises the KPI capability on the token.

Marks the KPI latest KPI-linked rate resolver as ready and emits KpisInitialized.

isCheckPointDate

function isCheckPointDate(uint256 _date, address _project) external view returns (bool exists_)

Checks whether a KPI data point exists for _project at exactly _date.

Parameters

Name	Type	Description
_date	uint256	Unix timestamp to look up.
_project	address	Address of the project to query.

Returns

Name	Type	Description
exists_	bool	true if a data point is registered for (project, date).

Events

KpiDataAdded

event KpiDataAdded(address indexed project, uint256 date, uint256 value)

Emitted when a new KPI data point is recorded.

Parameters

Name	Type	Description
project indexed	address	Address of the project the data point belongs to.
date	uint256	Unix timestamp identifying the data point.
value	uint256	KPI value recorded at date.

KpisInitialized

event KpisInitialized()

Emitted once when the KPI capability is initialised on a token.

Fires exclusively from initializeKpis.

Errors

AccountHasNoRole

error AccountHasNoRole(address account, bytes32 role)

Thrown when an account does not hold a required role.

Parameters

Name	Type	Description
account	address	The account that lacks the role.
role	bytes32	The role that is not held.

AssetNotOperational

error AssetNotOperational(bytes32 configId, uint256 versionId)

Raised by InitializerStorageWrapper.checkOperational (and the related isConfigVersionOperational helper) when an operation is attempted on a configuration version that has not yet been marked operational.

Parameters

Name	Type	Description
configId	bytes32	Resolver-proxy configuration whose operational status was checked.
versionId	uint256	Configuration version whose operational status was checked.

CouponNotFound

error CouponNotFound(uint256 couponID)

Reverts when a coupon identifier does not resolve to an existing corporate action.

Parameters

Name	Type	Description
couponID	uint256	The coupon identifier that was not found.

Deactivated

error Deactivated()

Thrown when an operation guarded by onlyActivated is attempted on a token whose deactivation flag has already been set.

FacetAlreadyRegistered

error FacetAlreadyRegistered(bytes32 facetId, uint256 lastVersion)

Raised when an initialiser tries to register a facet that already has a non-zero last registered version (i.e. the facet is being re-initialised on a fresh install).

Parameters

Name	Type	Description
facetId	bytes32	Identifier of the offending facet.
lastVersion	uint256	Last version recorded for that facet at the time of the check.

InvalidDate

error InvalidDate(uint256 providedDate, uint256 minDate, uint256 maxDate)

Thrown when _date falls outside the token's allowed [minDate, maxDate] window.

Parameters

Name	Type	Description
providedDate	uint256	The date supplied by the caller.
minDate	uint256	Lower bound of the valid date range.
maxDate	uint256	Upper bound of the valid date range.

InvalidDateRange

error InvalidDateRange(uint256 fromDate, uint256 toDate)

Thrown when the supplied date range is invalid (e.g. fromDate > toDate).

Parameters

Name	Type	Description
fromDate	uint256	Start of the requested range.
toDate	uint256	End of the requested range.

IsPaused

error IsPaused()

Thrown when an operation that requires the token to be unpaused is attempted while the token is paused (own flag or any external pause contract).

KpiDataAlreadyExists

error KpiDataAlreadyExists(uint256 date)

Thrown when a KPI data point already exists for the given date and project.

Parameters

Name	Type	Description
date	uint256	The duplicate date supplied by the caller.

UnexpectedError

error UnexpectedError(bytes4 _errorId)

Reverts when an unreachable validation state is detected.

Replaces assertions for defensive handling of logically impossible states.

Parameters

Name	Type	Description
_errorId	bytes4	Identifier of the unexpected validation condition.

UnrecognizedResolverProxyVersion

error UnrecognizedResolverProxyVersion(bytes8 _resolverProxyVersion)

Parameters

Name	Type	Description
_resolverProxyVersion	bytes8	proxy version that is not compatible with the BLR.

WalletRecovered
