DividendSecurityHoldersFacet

DividendSecurityHoldersFacet
Diamond facet exposing the read-only dividend holder queries (getDividendHolders, getTotalDividendHolders) under RESOLVER_KEY_DIVIDEND_SECURITY_HOLDERS.
Inherits the implementation from DividendSecurityHolders and satisfies IStaticFunctionSelectors so the Diamond resolver can register the two selectors. Carries no initializer — the facet has no storage of its own; dividend state is maintained by DividendStorageWrapper and bootstrapped through the writer facet.
Methods
getDividendHolders
function getDividendHolders(uint256 dividendId, uint256 pageIndex, uint256 pageLength) external view returns (address[] holders_)
Returns the page of holder addresses eligible for a given dividend.
Reverts through onlyMatchingActionType if dividendId does not match the dividend corporate action type at index dividendId - 1.
Parameters
| Name | Type | Description |
|---|---|---|
| dividendId | uint256 | undefined |
| pageIndex | uint256 | undefined |
| pageLength | uint256 | undefined |
Returns
| Name | Type | Description |
|---|---|---|
| holders_ | address[] | Holder addresses on the requested page, in storage order. |
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 |
getTotalDividendHolders
function getTotalDividendHolders(uint256 dividendId) external view returns (uint256)
Returns the total number of holders eligible for a given dividend.
Reverts through onlyMatchingActionType if dividendId does not match the dividend corporate action type at index dividendId - 1.
Parameters
| Name | Type | Description |
|---|---|---|
| dividendId | uint256 | undefined |
Returns
| Name | Type | Description |
|---|---|---|
| _0 | uint256 | Total number of eligible holders. |
initializeDividendSecurityHolders
function initializeDividendSecurityHolders() external nonpayable
Initialises the dividend security holders capability on the token.
Callable once; subsequent calls revert with FacetAlreadyRegistered. Requires DEFAULT_ADMIN_ROLE. Called by the factory during deployment.
Events
DividendSecurityHoldersInitialized
event DividendSecurityHoldersInitialized()
Emitted once when the dividend security holders capability is initialised on a token.
Fires exclusively from initializeDividendSecurityHolders.
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. |
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. |
SnapshotIdDoesNotExists
error SnapshotIdDoesNotExists(uint256 snapshotId)
Thrown when the requested snapshot identifier has never been taken on this token.
Parameters
| Name | Type | Description |
|---|---|---|
| snapshotId | uint256 | The unrecognised snapshot identifier that was supplied. |
SnapshotIdNull
error SnapshotIdNull()
Thrown when a snapshot identifier of zero is supplied; zero is reserved and never assigned to a valid snapshot.
UnrecognizedResolverProxyVersion
error UnrecognizedResolverProxyVersion(bytes8 _resolverProxyVersion)
Thrown when the provided proxy version does not match any BLR compatible standard.
Parameters
| Name | Type | Description |
|---|---|---|
| _resolverProxyVersion | bytes8 | proxy version that is not compatible with the BLR. |
WalletRecovered
error WalletRecovered()
Thrown when attempting to recover a wallet that has already been recovered.
WrongIndexForAction
error WrongIndexForAction(uint256 index, bytes32 actionType)
Thrown when a type-scoped index does not correspond to an existing action.
Parameters
| Name | Type | Description |
|---|---|---|
| index | uint256 | The out-of-range index that was provided. |
| actionType | bytes32 | The action type against which the index was validated. |
