Class Tcp.Write

java.lang.Object

akka.io.Tcp.WriteCommand

akka.io.Tcp.SimpleWriteCommand

akka.io.Tcp.Write

All Implemented Interfaces:

NoSerializationVerificationNeeded, SelectionHandler.HasFailureMessage, Tcp.Command, Tcp.Message, java.io.Serializable, scala.Equals, scala.Product

Enclosing class:

Tcp

public static final class Tcp.Write
extends Tcp.SimpleWriteCommand
implements scala.Product, scala.Serializable

Write data to the TCP connection. If no ack is needed use the special NoAck object. The connection actor will reply with a Tcp.CommandFailed message if the write could not be enqueued. If Tcp.SimpleWriteCommand.wantsAck() returns true, the connection actor will reply with the supplied Tcp.SimpleWriteCommand.ack() token once the write has been successfully enqueued to the O/S kernel. Note that this does not in any way guarantee that the data will be or have been sent! Unfortunately there is no way to determine whether a particular write has been sent by the O/S.
