Class Udp.Send

  extended by akka.io.Udp.Send
All Implemented Interfaces:
SelectionHandler.HasFailureMessage, Udp.Command, Udp.Message, java.io.Serializable, scala.Equals, scala.Product
Enclosing class:

public static class Udp.Send
extends java.lang.Object
implements Udp.Command, scala.Product, scala.Serializable

This message is understood by the “simple sender” which can be obtained by sending the Udp.SimpleSender query to the UdpExt.manager() as well as by the listener actors which are created in response to Udp.Bind. It will send the given payload data as one UDP datagram to the given target address. The UDP actor will respond with Udp.CommandFailed if the send could not be enqueued to the O/S kernel because the send buffer was full. If the given ack is not of type Udp.NoAck the UDP actor will reply with the given object as soon as the datagram has been successfully enqueued to the O/S kernel.

The sending UDP socket’s address belongs to the “simple sender” which does not handle inbound datagrams and sends from an ephemeral port; therefore sending using this mechanism is not suitable if replies are expected, use Udp.Bind in that case.
