class SQLRowStream extends ReadStream[JsonArray]

A ReadStream of Rows from the underlying RDBMS. This class follows the ReadStream semantics and will automatically close the underlying resources if all returned rows are returned. For cases where the results are ignored before the full processing of the returned rows is complete the close method **MUST** be called in order to release underlying resources.

The interface is minimal in order to support all SQL clients not just JDBC.

  7. def close(handler: Handler[AsyncResult[Unit]]): Unit

    Closes the stream/underlying cursor(s).

    Closes the stream/underlying cursor(s). The actual close happens asynchronously. * @param handler called when the stream/underlying cursor(s) is(are) closed

  8. def close(): Unit

    Closes the stream/underlying cursor(s).

    Closes the stream/underlying cursor(s). The actual close happens asynchronously.

  9. def closeFuture(): Future[Unit]

    Like close but returns a scala.concurrent.Future instead of taking an AsyncResultHandler.

  10. def column(name: String): Int

    Will convert the column name to the json array index.

    Will convert the column name to the json array index. * @param name the column name

    returns

    the json array index

  11. def columns(): Buffer[String]

    Returns all column names available in the underlying resultset.

    Returns all column names available in the underlying resultset. One needs to carefully use this method since in contrast to the singular version it does not perform case insensitive lookups or takes alias in consideration on the column names. * @return the list of columns names returned by the query

  12. def endHandler(endHandler: Handler[Unit]): SQLRowStream

    Set an end handler.

    Set an end handler. Once the stream has ended, and there is no more data to be read, this handler will be called. * @return a reference to this, so the API can be used fluently

  15. def exceptionHandler(handler: Handler[Throwable]): SQLRowStream

    Set an exception handler on the read stream.

    Set an exception handler on the read stream. * @param handler the exception handler

    returns

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

  16. def fetch(arg0: Long): ReadStream[JsonArray]

    Fetch the specified amount of elements.

    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. * @return a reference to this, so the API can be used fluently

    Set a data handler.

    Set a data handler. As data is read, the handler will be called with the data. * @return a reference to this, so the API can be used fluently

    Pause the ReadStream, it sets the buffer in fetch mode and clears the actual demand.

    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. * @return a reference to this, so the API can be used fluently

  27. def resultSetClosedHandler(handler: Handler[Unit]): SQLRowStream

    Event handler when a resultset is closed.

    Event handler when a resultset is closed. This is useful to request for more results. * @param handler called when the current result set is closed

  28. def resume(): SQLRowStream

    Resume reading, and sets the buffer in flowing mode.

    Resume reading, and sets the buffer in flowing mode.

    If the ReadStream has been paused, reading will recommence on it. * @return a reference to this, so the API can be used fluently
