        Description copied from class: DataStorage
        Implementation of getting a subsequence of this data storage. The validity of the arguments of this method do not need to be checked.
        Specified by:
        implSubsequence in class DataStorage
        Parameters:
        offset - The subsequence starting position.
        length - The subsequence length.
        Returns:
        Data storage that represents the specified part of this data storage.
        Throws:
        ApfloatRuntimeException

        Parameters:
        mode - Access mode for the array access: DataStorage.READ, DataStorage.WRITE or both.
        offset - Starting position of the array access in the data storage.
        length - Number of accessible elements in the array access.
        Returns:
        The array access.
