Interface RowStream<T>

All Superinterfaces:
ReadStream<T>, StreamBase

public interface RowStream<T> extends ReadStream<T>
A row oriented stream.
  • Method Details

    • rowDescriptor

      default RowDescriptor rowDescriptor()
      Describes rows emitted by this stream.

      This returns null until the first set of rows is fetched from the database.

    • exceptionHandler

      RowStream<T> exceptionHandler(Handler<Throwable> handler)
      Description copied from interface: ReadStream
      Set an exception handler on the read stream.
      Specified by:
      exceptionHandler in interface ReadStream<T>
      Specified by:
      exceptionHandler in interface StreamBase
      Parameters:
      handler - the exception handler
      Returns:
      a reference to this, so the API can be used fluently
    • handler

      RowStream<T> handler(Handler<T> 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<T>
      Returns:
      a reference to this, so the API can be used fluently
    • pause

      RowStream<T> 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<T>
      Returns:
      a reference to this, so the API can be used fluently
    • resume

      RowStream<T> 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<T>
      Returns:
      a reference to this, so the API can be used fluently
    • endHandler

      RowStream<T> endHandler(Handler<Void> endHandler)
      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<T>
      Returns:
      a reference to this, so the API can be used fluently
    • fetch

      RowStream<T> 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<T>
      Returns:
      a reference to this, so the API can be used fluently
    • close
