    Modifier and Type | Method and Description
    --- | ---
    `CassandraRowStream` | `endHandler(Handler<Void> handler)` Set an end handler.
    `CassandraRowStream` | `exceptionHandler(Handler<Throwable> handler)` Set an exception handler on the read stream.

    - #### exceptionHandler

          CassandraRowStream exceptionHandler(Handler<Throwable> handler)

      Description copied from interface: `ReadStream`
      Set an exception handler on the read stream.
      Specified by:
        `exceptionHandler` in interface `ReadStream<com.datastax.driver.core.Row>`
      Specified by:
        `exceptionHandler` in interface `StreamBase`
      Parameters:
        `handler` - the exception handler
      Returns:
        a reference to this, so the API can be used fluently

    - #### handler

          CassandraRowStream handler(Handler<com.datastax.driver.core.Row> handler)

      Description copied from interface: `ReadStream`
      Set a data handler. As data is read, the handler will be called with the data.
      Specified by:
        `handler` in interface `ReadStream<com.datastax.driver.core.Row>`
      Returns:
        a reference to this, so the API can be used fluently

    - #### pause

          CassandraRowStream pause()

      Description copied from interface: `ReadStream`
      Pause the `ReadStream`, it sets the buffer in `fetch` mode and clears the actual demand.

      While it's paused, no data will be sent to the data `handler`.

      Specified by:
        `pause` in interface `ReadStream<com.datastax.driver.core.Row>`
      Returns:
        a reference to this, so the API can be used fluently

    - #### resume

          CassandraRowStream resume()

      Description copied from interface: `ReadStream`
      Resume reading, and sets the buffer in `flowing` mode.

      If the `ReadStream` has been paused, reading will recommence on it.
      Specified by:
        `resume` in interface `ReadStream<com.datastax.driver.core.Row>`
      Returns:
        a reference to this, so the API can be used fluently

    - #### endHandler

          CassandraRowStream endHandler(Handler<Void> handler)

      Description copied from interface: `ReadStream`
      Set an end handler. Once the stream has ended, and there is no more data to be read, this handler will be called.
      Specified by:
        `endHandler` in interface `ReadStream<com.datastax.driver.core.Row>`
      Returns:
        a reference to this, so the API can be used fluently

    - #### fetch

          CassandraRowStream fetch(long l)

      Description copied from interface: `ReadStream`
      Fetch the specified `amount` of elements. If the `ReadStream` has been paused, reading will recommence with the specified `amount` of items, otherwise the specified `amount` will be added to the current stream demand.
      Specified by:
        `fetch` in interface `ReadStream<com.datastax.driver.core.Row>`
      Returns:
        a reference to this, so the API can be used fluently
