Class Udp.Send
java.lang.Object
akka.io.Udp.Send
- All Implemented Interfaces:
- SelectionHandler.HasFailureMessage, Udp.Command, Udp.Message, java.io.Serializable, scala.Equals, scala.Product
- Enclosing class:
- Udp
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.
