The common type of all commands supported by the UDP implementation.
When a command fails it will be replied to with this message type, wrapping the failing command object.
Send this message to the UdpExt#manager in order to bind to a local
port (optionally with the chosen localAddress
) and create a UDP socket
which is restricted to sending to and receiving from the given remoteAddress
.
Send this message to the UdpExt#manager in order to bind to a local

) and create a UDP socket
which is restricted to sending to and receiving from the given remoteAddress
.
All received datagrams will be sent to the designated handler
actor.
This message is sent by the connection actor to the actor which sent the Connect message when the UDP socket has been bound to the local and remote addresses given.
This message is sent by the connection actor to the actor which sent the
Disconnect
message when the UDP socket has been closed.
The common type of all events emitted by the UDP implementation.
Each Send can optionally request a positive acknowledgment to be sent to the commanding actor.
Each Send can optionally request a positive acknowledgment to be sent to the commanding actor. If such notification is not desired the Send#ack must be set to an instance of this class. The token contained within can be used to recognize which write failed when receiving a CommandFailed message.
When a connection actor receives a datagram from its socket it will send it to the handler designated in the Udp.Bind message using this message type.
This message is understood by the connection actors to send data to their designated destination.
This message is understood by the connection actors to send data to their
designated destination. The connection actor will respond with
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 NoAck
the connection actor will reply with the given object as soon as the datagram
has been successfully enqueued to the O/S kernel.
Send this message to a connection actor (which had previously sent the Connected message) in order to close the socket.
Send this message to a connection actor (which had previously sent the Connected message) in order to close the socket. The connection actor will reply with a Disconnected message.
Default NoAck instance which is used when no acknowledgment information is explicitly provided.
Default NoAck instance which is used when no acknowledgment information is
explicitly provided. Its “token” is null
.
This message must be sent to the listener actor to re-enable reading from
the socket after a SuspendReading
command.
Send this message to a listener actor (which sent a Udp.Bound message) to have it stop reading datagrams from the network.
Send this message to a listener actor (which sent a Udp.Bound message) to
have it stop reading datagrams from the network. If the O/S kernel’s receive
buffer runs full then subsequent datagrams will be silently discarded.
Re-enable reading from the socket using the ResumeReading
command.

UDP Extension for Akka’s IO layer.
This extension implements the connectionless UDP protocol with calling
connect
on the underlying sockets, i.e. with restricting from whom data can be received. For “unconnected” UDP mode see Udp.For a full description of the design and philosophy behind this IO implementation please refer to the Akka online documentation.
The Java API for generating UDP commands is available at UdpConnectedMessage.
