Syntax

public class TcpExt : IExtension

Fields

BindShutdownTimeout

TBD

Declaration

protected readonly TimeSpan BindShutdownTimeout

Field Value

Type	Description
TimeSpan

Methods

Bind(String, Int32, Int32, IImmutableList<Inet.SocketOption>, Boolean, Nullable<TimeSpan>)

Creates a Tcp.ServerBinding instance which represents a prospective TCP server binding on the given host and port/>.

Please note that the startup of the server is asynchronous, i.e. after materializing the enclosing RunnableGraph<TMat> the server is not immediately available. Only after the materialized future completes is the server ready to accept client connections.

Declaration

public Source<Tcp.IncomingConnection, Task<Tcp.ServerBinding>> Bind(string host, int port, int backlog = 100, IImmutableList<Inet.SocketOption> options = null, bool halfClose = false, TimeSpan? idleTimeout = null)

Parameters

Type	Name	Description
String	host	The host to listen on
Int32	port	The port to listen on
Int32	backlog	Controls the size of the connection backlog
System.Collections.Immutable.IImmutableList<Inet.SocketOption>	options	TCP options for the connections, see Tcp for details
Boolean	halfClose	Controls whether the connection is kept open even after writing has been completed to the accepted TCP connections. If set to true, the connection will implement the TCP half-close mechanism, allowing the client to write to the connection even after the server has finished writing. The TCP socket is only closed after both the client and server finished writing. If set to false, the connection will immediately closed once the server closes its write side, independently whether the client is still attempting to write. This setting is recommended for servers, and therefore it is the default setting.
Nullable<TimeSpan>	idleTimeout	TBD

Returns

Type	Description

BindAndHandle(Flow<ByteString, ByteString, NotUsed>, IMaterializer, String, Int32, Int32, IImmutableList<Inet.SocketOption>, Boolean, Nullable<TimeSpan>)

Creates a Tcp.ServerBinding instance which represents a prospective TCP server binding on the given host and port/> handling the incoming connections using the provided Flow.

Please note that the startup of the server is asynchronous, i.e. after materializing the enclosing RunnableGraph<TMat> the server is not immediately available. Only after the materialized future completes is the server ready to accept client connections.

Declaration

public Task<Tcp.ServerBinding> BindAndHandle(Flow<ByteString, ByteString, NotUsed> handler, IMaterializer materializer, string host, int port, int backlog = 100, IImmutableList<Inet.SocketOption> options = null, bool halfClose = false, TimeSpan? idleTimeout = null)

Parameters

Type	Name	Description
Flow<ByteString, ByteString, NotUsed>	handler	A Flow that represents the server logic
IMaterializer	materializer	TBD
String	host	The host to listen on
Int32	port	The port to listen on
Int32	backlog	Controls the size of the connection backlog
System.Collections.Immutable.IImmutableList<Inet.SocketOption>	options	TCP options for the connections, see Tcp for details
Boolean	halfClose	Controls whether the connection is kept open even after writing has been completed to the accepted TCP connections. If set to true, the connection will implement the TCP half-close mechanism, allowing the client to write to the connection even after the server has finished writing. The TCP socket is only closed after both the client and server finished writing. If set to false, the connection will immediately closed once the server closes its write side, independently whether the client is still attempting to write.

Nullable<TimeSpan>	idleTimeout	TBD

Returns

Type	Description
Task<Tcp.ServerBinding>	TBD

OutgoingConnection(EndPoint, EndPoint, IImmutableList<Inet.SocketOption>, Boolean, Nullable<TimeSpan>, Nullable<TimeSpan>)

Creates a Tcp.OutgoingConnection instance representing a prospective TCP client connection to the given endpoint.

Note that the ByteString chunk boundaries are not retained across the network, to achieve application level chunks you have to introduce explicit framing in your streams, for example using the Framing stages.

Declaration

public Flow<ByteString, ByteString, Task<Tcp.OutgoingConnection>> OutgoingConnection(EndPoint remoteAddress, EndPoint localAddress = null, IImmutableList<Inet.SocketOption> options = null, bool halfClose = true, TimeSpan? connectionTimeout = null, TimeSpan? idleTimeout = null)

Parameters

Type	Name	Description
EndPoint	remoteAddress	The remote address to connect to
EndPoint	localAddress	Optional local address for the connection
System.Collections.Immutable.IImmutableList<Inet.SocketOption>	options	TCP options for the connections, see Tcp for details
Boolean	halfClose	Controls whether the connection is kept open even after writing has been completed to the accepted TCP connections. If set to true, the connection will implement the TCP half-close mechanism, allowing the server to write to the connection even after the client has finished writing.The TCP socket is only closed after both the client and server finished writing. This setting is recommended for clients and therefore it is the default setting. If set to false, the connection will immediately closed once the client closes its write side, independently whether the server is still attempting to write.
Nullable<TimeSpan>	connectionTimeout	TBD
Nullable<TimeSpan>	idleTimeout	TBD

Returns

Type	Description
Flow<ByteString, ByteString, Task<Tcp.OutgoingConnection>>	TBD

OutgoingConnection(String, Int32)

Creates an Tcp.OutgoingConnection without specifying options. It represents a prospective TCP client connection to the given endpoint.

Note that the ByteString chunk boundaries are not retained across the network, to achieve application level chunks you have to introduce explicit framing in your streams, for example using the Framing stages.

Declaration

public Flow<ByteString, ByteString, Task<Tcp.OutgoingConnection>> OutgoingConnection(string host, int port)

Parameters

Type	Name	Description
String	host	TBD
Int32	port	TBD

Returns

Type	Description
