IFreezeAtSnapshotByPartition

Interface exposing partition-aware historical frozen-balance queries against captured snapshots.

Read-only counterpart of IFreezeAtSnapshot for multi-partition mode. Returns the frozen amount on a specific partition as it was at the time the snapshot was taken, including time-based adjustments scheduled before that block.

Methods

frozenBalanceOfAtSnapshotByPartition

function frozenBalanceOfAtSnapshotByPartition(bytes32 _partition, uint256 _snapshotID, address _tokenHolder) external view returns (uint256 balance_)

Returns the frozen balance of an account for a given partition at the time of a given snapshot.

Parameters

Name	Type	Description
_partition	bytes32	The partition the frozen balance is queried in.
_snapshotID	uint256	The identifier of the snapshot to query.
_tokenHolder	address	The address whose frozen balance is being queried.

Returns

Name	Type	Description
balance_	uint256	The frozen balance of _tokenHolder on _partition at snapshot _snapshotID.
