trait ReadStream[T] extends StreamBase

Represents a stream of items that can be read from.

Any class that implements this interface can be used by a io.vertx.scala.core.streams.Pump to pump data from it to a io.vertx.scala.core.streams.WriteStream.

Streaming mode

The stream is either in flowing or fetch mode.

Initially the stream is in flowing mode.

  • When the stream is in flowing mode, elements are delivered to the handler.
  • When the stream is in fetch mode, only the number of requested elements will be delivered to the handler.

The mode can be changed with the io.vertx.scala.core.streams.ReadStream#pause, io.vertx.scala.core.streams.ReadStream#resume and io.vertx.scala.core.streams.ReadStream#fetch methods:

  2. abstract def endHandler(endHandler: Handler[Unit]): ReadStream[T]

    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

  3. abstract def exceptionHandler(handler: Handler[Throwable]): ReadStream[T]

    Set an exception handler on the read stream.

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

  4. abstract def fetch(amount: Long): ReadStream[T]

    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

  5. abstract def handler(handler: Handler[T]): ReadStream[T]

    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

  6. abstract def pause(): ReadStream[T]

    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

  7. abstract def resume(): ReadStream[T]

    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
