    TimingInformation, containing processing time.

Static Private _fetchResultPages

  • _fetchResultPages(txnId: string, executeResult: ExecuteStatementResult, communicator: Communicator): Promise<Result>

  • Fetches all subsequent Pages given an initial Page, places each value of each Page in an Ion value.

    Parameters

    • txnId: string

      The ID of the transaction the statement was executed in.

    • executeResult: ExecuteStatementResult

    Returns Promise<Result>

    Promise which fulfills with a Result, containing a list of Ion values, representing all the returned values of the result set, number of IOs for the request, and the time spent processing the request.

Static Private _readResultReadable

  • _readResultReadable(resultReadable: ResultReadable): Promise<Value[]>

  • Helper method that reads a ResultReadable and extracts the results, placing them in an array of Ion values.

    Parameters

    Returns Promise<Value[]>

    Promise which fulfills with a list of Ion values, representing all the returned values of the result set.

Static bufferResultReadable

  • Static method that creates a Result object by reading and buffering the contents of a ResultReadable.

    Parameters

    • resultReadable: ResultReadable

      A ResultReadable object to convert to a Result object.
