Methods

Private attachListenerForNewEvents

  • Parameters

    • eventFilter: EventFilter
    • listener: Listener

    Returns void

connect

  • This method is used to connect the wallet signer to the DesmoHub contract.

    Returns void

disableTDD

  • This method is used to call the homonym function on the smart contract that disable a TDD. It produce an event when the transaction is sent. It is possible to get the result of the transaction by subscribing to the tddDisabled$ observable, after having activated the listeners.

    Returns Promise<void>

enableTDD

  • This method is used to call the homonym function on the smart contract that enable a TDD. It produce an event when the transaction is sent. It is possible to get the result of the transaction by subscribing to the tddEnabled$ observable, after having activated the listeners.

    Returns Promise<void>

getNewRequestID

  • This method is used to call the homonym function on the smart contract to get a new Request id. It produce an event when the transaction is sent. It is possible to get the result of the transaction by subscribing to the requestID$ observable, after having activated the listeners.

    Returns Promise<void>

getScoresByRequestID

  • Get the scores relative to a request id.

    Returns

    Parameters

    • requestID: Bytes

    Returns Promise<Bytes>

getTDD

getTDDByRequestID

  • Get TDD by request id.

    Returns

    Parameters

    • requestID: Bytes

    Returns Promise<string[]>

getTDDStorageLength

  • Returns

    the length of the TDD storage.

    Returns Promise<BigNumber>

registerTDD

  • This method is used to call the homonym function on the smart contract that register a new TDD. It produce an event when the transaction is sent. It is possible to get the result of the transaction by subscribing to the tddCreated$ observable, after having activated the listeners.

    Parameters

    • tddUrl: string

      the url of the TDD to be created.

    Returns Promise<void>

startListeners

  • This method start the listeners. It is possible to get the result of a transction by subscribing to the following observables:

    • transactionSent$
    • tddCreated$
    • tddDisabled$
    • tddEnabled$
    • requestID$

    Returns Promise<void>
