Methods
allBalances
▸ allBalances(paginationOpts?: PaginationOptions): Promise‹ResultSet‹IdentityBalance››
Defined in src/api/entities/Checkpoint.ts:108
Retrieve all Asset Holder balances at this Checkpoint
note supports pagination
note current Asset holders who didn't hold any tokens when the Checkpoint was created will be listed with a balance of 0. This arises from a chain storage optimization and pagination. @see balance for a more detailed explanation of the logic
Parameters:
paginationOpts?
Returns: Promise‹ResultSet‹IdentityBalance››
balance
▸ balance(args?: undefined | object): Promise‹BigNumber›
Defined in src/api/entities/Checkpoint.ts:201
Retrieve the balance of a specific Asset Holder Identity at this Checkpoint
note A checkpoint only records balances when they change. The implementation is to query for all balance updates for [ticker, did] pair. If no balance updates have happened since the Checkpoint has been created, then the storage will not have an entry for the user. Instead the current balance should be used. The balance is stored only when the Identity makes a transaction after a Checkpoint is created. This helps keep storage usage to a minimum
Parameters:
args?
undefined | object
Returns: Promise‹BigNumber›
createdAt
▸ createdAt(): Promise‹Date›
Defined in src/api/entities/Checkpoint.ts:86
Retrieve this Checkpoint's creation date
Returns: Promise‹Date›
exists
▸ exists(): Promise‹boolean›
Defined in src/api/entities/Checkpoint.ts:245
Determine whether this Checkpoint exists on chain
Returns: Promise‹boolean›
isEqual
▸ isEqual(entity: Entity‹unknown, unknown›): boolean
Inherited from CheckpointSchedule.isEqual
Defined in src/api/entities/Entity.ts:61
Determine whether this Entity is the same as another one
Parameters:
entity
Returns: boolean
toHuman
▸ toHuman(): HumanReadable
Defined in src/api/entities/Checkpoint.ts:265
Return the Checkpoint's ticker and identifier
Returns: HumanReadable
totalSupply
▸ totalSupply(): Promise‹BigNumber›
Defined in src/api/entities/Checkpoint.ts:68
Retrieve the Asset's total supply at this checkpoint
Returns: Promise‹BigNumber›
