ILockAtSnapshotByPartition
Interface for querying a token holder's locked balance for a specific partition at the time of a previously taken snapshot.
Reads are delegated to SnapshotsStorageWrapper and depend on the snapshot index recorded by takeSnapshot. Reverts with SnapshotIdNull when _snapshotID == 0 and with SnapshotIdDoesNotExists for unknown identifiers.
Methods
initializeLockAtSnapshotByPartition
function initializeLockAtSnapshotByPartition() external nonpayable
Initialises the lock-at-snapshot-by-partition capability on the token.
Callable once; subsequent calls revert with FacetAlreadyRegistered. Requires DEFAULT_ADMIN_ROLE. Called by the factory during deployment.
lockedBalanceOfAtSnapshotByPartition
function lockedBalanceOfAtSnapshotByPartition(bytes32 _partition, uint256 _snapshotID, address _tokenHolder) external view returns (uint256 balance_)
Returns the locked balance of a token holder for a given partition at the time of a given snapshot.
Parameters
| Name | Type | Description |
|---|---|---|
| _partition | bytes32 | The partition identifier. |
| _snapshotID | uint256 | The snapshot identifier returned by a prior takeSnapshot call. |
| _tokenHolder | address | The address of the token holder. |
Returns
| Name | Type | Description |
|---|---|---|
| balance_ | uint256 | The locked balance of _tokenHolder in _partition recorded at _snapshotID. |
Events
LockAtSnapshotByPartitionInitialized
event LockAtSnapshotByPartitionInitialized()
Emitted once when the lock-at-snapshot-by-partition capability is initialised on a token.
Fires exclusively from initializeLockAtSnapshotByPartition.
