java.lang.Object akka.io.Tcp
public class Tcp
TCP Extension for Akka’s IO layer.
For a full description of the design and philosophy behind this IO implementation please refer to the Akka online documentation.
In order to open an outbound connection send a Tcp.Connect
message
to the TcpExt.manager()
.
In order to start listening for inbound connetions send a Tcp.Bind
message to the TcpExt.manager()
.
The Java API for generating TCP commands is available at TcpMessage
.
Nested Class Summary | |
---|---|
static class |
Tcp.Abort$
An abort operation will not flush pending writes and will issue a TCP ABORT command to the O/S kernel which should result in a TCP_RST packet being sent to the peer. |
static class |
Tcp.Aborted$
The connection has been aborted in response to an Abort command. |
static class |
Tcp.Bind
The Bind message is send to the TCP manager actor, which is obtained via TcpExt.manager() in order to bind to a listening socket. |
static class |
Tcp.Bind$
|
static class |
Tcp.Bound
The sender of a Tcp.Bind command will—in case of success—receive confirmation
in this form. |
static class |
Tcp.Bound$
|
static class |
Tcp.Close$
A normal close operation will first flush pending writes and then close the socket. |
static interface |
Tcp.CloseCommand
Common interface for all commands which aim to close down an open connection. |
static class |
Tcp.Closed$
The connection has been closed normally in response to a Close command. |
static interface |
Tcp.Command
This is the common trait for all commands understood by TCP actors. |
static class |
Tcp.CommandFailed
Whenever a command cannot be completed, the queried actor will reply with this message, wrapping the original command which failed. |
static class |
Tcp.CommandFailed$
|
static class |
Tcp.CompoundWrite
A write command which aggregates two other write commands. |
static class |
Tcp.CompoundWrite$
|
static class |
Tcp.ConfirmedClose$
A confirmed close operation will flush pending writes and half-close the connection, waiting for the peer to close the other half. |
static class |
Tcp.ConfirmedClosed$
The connection has been half-closed by us and then half-close by the peer in response to a ConfirmedClose command. |
static class |
Tcp.Connect
The Connect message is sent to the TCP manager actor, which is obtained via TcpExt.manager() . |
static class |
Tcp.Connect$
|
static class |
Tcp.Connected
The connection actor sends this message either to the sender of a Tcp.Connect
command (for outbound) or to the handler for incoming connections designated
in the Tcp.Bind message. |
static class |
Tcp.Connected$
|
static interface |
Tcp.ConnectionClosed
This is the common interface for all events which indicate that a connection has been closed or half-closed. |
static class |
Tcp.ErrorClosed
The connection has been closed due to an IO error. |
static class |
Tcp.ErrorClosed$
|
static interface |
Tcp.Event
Common interface for all events generated by the TCP layer actors. |
static interface |
Tcp.Message
The common interface for Tcp.WriteCommand and Tcp.Event . |
static class |
Tcp.NoAck
Each Tcp.WriteCommand can optionally request a positive acknowledgment to be sent
to the commanding actor. |
static class |
Tcp.NoAck$
Default Tcp.NoAck instance which is used when no acknowledgment information is
explicitly provided. |
static class |
Tcp.PeerClosed$
The peer has closed its writing half of the connection. |
static class |
Tcp.Received
Whenever data are read from a socket they will be transferred within this class to the handler actor which was designated in the Tcp.Register message. |
static class |
Tcp.Received$
|
static class |
Tcp.Register
This message must be sent to a TCP connection actor after receiving the Tcp.Connected message. |
static class |
Tcp.Register$
|
static class |
Tcp.ResumeAccepting
This message enables the accepting of the next connection if read throttling is enabled for connection actors. |
static class |
Tcp.ResumeAccepting$
|
static class |
Tcp.ResumeReading$
This command needs to be sent to the connection actor after a SuspendReading
command in order to resume reading from the socket. |
static class |
Tcp.ResumeWriting$
When useResumeWriting is in effect as was indicated in the Tcp.Register message
then this command needs to be sent to the connection actor in order to re-enable
writing after a Tcp.CommandFailed event. |
static class |
Tcp.SimpleWriteCommand
Common supertype of Tcp.Write and Tcp.WriteFile . |
static class |
Tcp.SO$
Scala API: this object contains all applicable socket options for TCP. |
static class |
Tcp.SuspendReading$
Sending this command to the connection actor will disable reading from the TCP socket. |
static class |
Tcp.Unbind$
In order to close down a listening socket, send this message to that socket’s actor (that is the actor which previously had sent the Tcp.Bound message). |
static interface |
Tcp.Unbound
The sender of an Unbind command will receive confirmation through this
message once the listening socket has been closed. |
static class |
Tcp.Unbound$
|
static class |
Tcp.Write
Write data to the TCP connection. |
static class |
Tcp.Write$
|
static class |
Tcp.WriteCommand
Common interface for all write commands, currently Tcp.Write , Tcp.WriteFile and Tcp.CompoundWrite . |
static class |
Tcp.WriteCommand$
|
static class |
Tcp.WriteFile
Write count bytes starting at position from file at filePath to the connection. |
static class |
Tcp.WriteFile$
|
static interface |
Tcp.WritingResumed
When useResumeWriting is in effect as indicated in the Tcp.Register message,
the ResumeWriting command will be acknowledged by this message type, upon
which it is safe to send at least one write. |
static class |
Tcp.WritingResumed$
|
