    - #### onError

          WriteStreamSubscriber<R> onError​(Consumer<? super Throwable> handler)

      Sets the handler to invoke if the `Flowable` that was subscribed to terminates with an error.

      The underlying `WriteStream.end()` method is not invoked in this case.

      Returns:
        a reference to this, so the API can be used fluently

    - #### onWriteStreamError

          WriteStreamSubscriber<R> onWriteStreamError​(Consumer<? super Throwable> handler)

      Sets the handler to invoke if the adapted `WriteStream` fails.

      The underlying `WriteStream.end()` method is not invoked in this case.

      Returns:
        a reference to this, so the API can be used fluently

    - #### onWriteStreamEnd

          WriteStreamSubscriber<R> onWriteStreamEnd​(Action handler)

      Sets the handler to invoke when the adapted `WriteStream` ends successfully.
      Returns:
        a reference to this, so the API can be used fluently

    - #### onWriteStreamEndError

          WriteStreamSubscriber<R> onWriteStreamEndError​(Consumer<? super Throwable> handler)

      Sets the handler to invoke when the adapted `WriteStream` ends with an error.
      Returns:
        a reference to this, so the API can be used fluently
