Package io.vertx.rxjava3.core.eventbus

Class MessageConsumer<T>

java.lang.Object
io.vertx.rxjava3.core.eventbus.MessageConsumer<T>
All Implemented Interfaces:
RxDelegate, ReadStream<Message<T>>, StreamBase
public class MessageConsumer<T> extends Object implements RxDelegate, ReadStream<Message<T>>
An event bus consumer object representing a stream of message to an EventBus address that can be read from.

The EventBus.consumer(io.vertx.core.eventbus.MessageConsumerOptions) or EventBus.localConsumer(java.lang.String) creates a new consumer, the returned consumer is not yet registered against the event bus. Registration is effective after the handler(io.vertx.core.Handler<io.vertx.rxjava3.core.eventbus.Message<T>>) method is invoked.

The consumer is unregistered from the event bus using the unregister() method or by calling the handler(io.vertx.core.Handler<io.vertx.rxjava3.core.eventbus.Message<T>>) with a null value..

NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.

      Pipe this ReadStream to the WriteStream.

      Elements emitted by this stream will be written to the write stream until this stream ends or fails.

      Specified by:
      pipeTo in interface ReadStream<T>
      Parameters:
      dst - the destination write stream
      Returns:
      a future notified when the write stream will be ended with the outcome

      Pipe this ReadStream to the WriteStream.

      Elements emitted by this stream will be written to the write stream until this stream ends or fails.

      Specified by:
      rxPipeTo in interface ReadStream<T>
      Parameters:
      dst - the destination write stream
      Returns:

    • exceptionHandler

      public MessageConsumer<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

      public MessageConsumer<T> handler(Handler<Message<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

      public MessageConsumer<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.
