Constructors

constructor

• new OffChainListBase(): OffChainListBase

• Inherited from Struct({ /** The root hash of the Merkle tree representing the whitelist. */ root: Field, }).constructor

  Returns OffChainListBase

Methods

getValue

• getValue(key: Field, storage: Storage, name?: string): Promise<FieldOption>

• The function fetches a whitelisted amount associated with a given key using a map and returns it as a FieldOption.

  ---

  Parameters

  • key: Field

    The key parameter is of type Field, which represents a field element in the context of a cryptographic system.

  • storage: Storage

  • name: string = "offchain-map"

  Returns Promise<FieldOption>

  The getValue function returns a Promise that resolves to a FieldOption object. This object contains a value property representing the amount retrieved from a map based on the provided key. The isSome property indicates whether the value is present or not. The value is not present if the list is NOT empty and the key is NOT in the map. The value is present if the list IS empty or the key IS in the map. The value is present and equals to Field(0) if the list IS empty.

isNone

• isNone(): Bool

• Returns Bool

isSome

• isSome(): Bool

• Returns Bool

load

• load(storage: Storage, name?: string): Promise<OffchainMapOption>

• Parameters

  • storage: Storage

  • name: string = "offchain-map"

  Returns Promise<OffchainMapOption>

toString

• toString(): string

• Returns string

staticcreate

• create(params: { data?: object; list: OffChainMapEntry[] | { key: string; value?: number }[]; name?: string }): Promise<{ json: OffchainMapSerialized; listBase: OffChainListBase }>

• Creates a new OffchainListBase

  ---

  Parameters

  • params: { data?: object; list: OffChainMapEntry[] | { key: string; value?: number }[]; name?: string }

    The parameters for creating the list.

  • optionaldata: object

    The JSON data that should be added to the IPFS storage that represent the initial data

  • list: OffChainMapEntry[] | { key: string; value?: number }[]

    The list of entries to be added to the map.

  • optionalname: string

  Returns Promise<{ json: OffchainMapSerialized; listBase: OffChainListBase }>

  A new OffChainList instance.

staticempty

• empty(): OffChainListBase

• Returns OffChainListBase

staticfromString

• fromString(str: string): OffChainListBase

• Parameters

  • str: string

  Returns OffChainListBase
