Defined in src/api/entities/Checkpoint.ts:46

Checkpoint identifier number

Methods

allBalances

allBalances(paginationOpts?: PaginationOptions): Promise‹ResultSetIdentityBalance››

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:

NameType

paginationOpts?

Returns: Promise‹ResultSetIdentityBalance››


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:

NameType

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›

Overrides Entity.exists

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:

NameType

entity

Entity‹unknown, unknown›

Returns: boolean


toJson

toJson(): HumanReadable

Overrides Entity.toJson

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›


Static generateUuid

generateUuidIdentifiers›(identifiers: Identifiers): string

Inherited from CheckpointSchedule.generateUuid

Defined in src/api/entities/Entity.ts:14

Generate the Entity's UUID from its identifying properties

Type parameters:

Parameters:

NameTypeDescription

Identifiers

Returns: string


Static unserialize

unserializeIdentifiers›(serialized: string): Identifiers

Inherited from CheckpointSchedule.unserialize

Defined in src/api/entities/Entity.ts:23

Unserialize a UUID into its Unique Identifiers

Type parameters:
