public static class StreamChannel.StreamChannelImpl extends Object implements StreamChannel

  • Constructor Details

    • StreamChannelImpl

      public StreamChannelImpl(io.vertx.core.net.StreamChannel delegate)
      Create a new instance of StreamChannel.StreamChannelImpl delegating to the given (non-null) instance of StreamChannel.

  • Method Details

    • getDelegate

      public io.vertx.core.net.StreamChannel getDelegate()
      Get the delegate instance.

      This method returns the instance on which this shim is delegating the calls. And so, give you access to the bare API.

      Specified by:
      getDelegate in interface MutinyDelegate
      Specified by:
      getDelegate in interface ReadStream<io.vertx.core.buffer.Buffer>
      Specified by:
      getDelegate in interface StreamBase
      Specified by:
      getDelegate in interface StreamChannel
      Specified by:
      getDelegate in interface WriteStream<io.vertx.core.buffer.Buffer>
      Returns:
      the delegate instance

    • write

      @CheckReturnValue public io.smallrye.mutiny.Uni<Void> write(String str)
      Write a String to the connection, encoded in UTF-8.

      Unlike the bare Vert.x variant, this method returns a Uni. The uni emits the result of the operation as item. If the operation fails, the uni emits the failure.

      Don't forget to subscribe on it to trigger the operation.

      Specified by:
      write in interface StreamChannel
      Parameters:
      str - the string to write
      Returns:
      A Uni representing the asynchronous result of this operation.
      See Also:
      • StreamChannel.write(String)

    • writeAndAwait

      public void writeAndAwait(String str)
      Write a String to the connection, encoded in UTF-8.

      Unlike the bare Vert.x variant, this method returns a Void. This method awaits indefinitely for the completion of the underlying asynchronous operation. If the operation completes successfully, the result is returned, otherwise the failure is thrown (potentially wrapped in a RuntimeException).

      Parameters:
      str - the string to write
      See Also:
      • StreamChannel.write(String)

    • writeAndForget

      public StreamChannel.StreamChannelImpl writeAndForget(String str)
      Write a String to the connection, encoded in UTF-8.

      Unlike the bare Vert.x variant, this method ignores the Void result or any failure.

      Parameters:
      str - the string to write
      Returns:
      The current instance to chain operations if needed.
      See Also:
      • StreamChannel.write(String)

    • write

      @CheckReturnValue public io.smallrye.mutiny.Uni<Void> write(String str, String enc)
      Write a String to the connection, encoded using the encoding enc.

      Unlike the bare Vert.x variant, this method returns a Uni. The uni emits the result of the operation as item. If the operation fails, the uni emits the failure.

    • write

      @CheckReturnValue public io.smallrye.mutiny.Uni<Void> write(io.vertx.core.buffer.Buffer arg0)
      Write some data to the stream.

      The data is usually put on an internal write queue, and the write actually happens asynchronously. To avoid running out of memory by putting too much on the write queue, check the writeQueueFull() method before writing. This is done automatically if using a Pipe.

      When the data is moved from the queue to the actual medium, the returned Future will be completed with the write result, e.g the uni is succeeded when a server HTTP response buffer is written to the socket and failed if the remote client has closed the socket while the data was still pending for write.

      Unlike the bare Vert.x variant, this method returns a Uni. The uni emits the result of the operation as item. If the operation fails, the uni emits the failure.
