getQualifier

Constructor Details

TcpNetServerConnectionFactory

public TcpNetServerConnectionFactory(int port)

Listens for incoming connections on the port.

Parameters:

port - The port.

Method Details

getComponentType

public String getComponentType()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this method to provide component type information.

Specified by:

getComponentType in interface NamedComponent

Overrides:

getComponentType in class IntegrationObjectSupport

getPort

public int getPort()

Description copied from interface: TcpServerConnectionFactory

Return the port this server is listening on. If the factory is configured to listen on a random port (0), this will return the actual port after the factory is started. It may return the previous value if the factory is stopped.

Specified by:

getPort in interface TcpServerConnectionFactory

Overrides:

getPort in class AbstractConnectionFactory

Returns:

the port

getServerSocketAddress

@Nullable
public SocketAddress getServerSocketAddress()

Description copied from interface: TcpServerConnectionFactory

Return the SocketAddress that the underlying ServerSocket is bound to.

Specified by:

getServerSocketAddress in interface TcpServerConnectionFactory

Overrides:

getServerSocketAddress in class AbstractServerConnectionFactory

Returns:

the socket address.

setTcpSocketFactorySupport

public void setTcpSocketFactorySupport(TcpSocketFactorySupport tcpSocketFactorySupport)

Set the TcpSocketFactorySupport used to create server sockets.

Parameters:

tcpSocketFactorySupport - the TcpSocketFactorySupport

setTcpNetConnectionSupport

public void setTcpNetConnectionSupport(TcpNetConnectionSupport connectionSupport)

Set the TcpNetConnectionSupport to use to create connection objects.

Parameters:

connectionSupport - the connection support.

Since:

5.0

run

public void run()

If no listener registers, exits. Accepts incoming connections and creates TcpConnections for each new connection. Invokes {AbstractServerConnectionFactory.initializeConnection(TcpConnectionSupport, Socket) and executes the connection Runnable.run() using the task executor. I/O errors on the server socket/channel are logged and the factory is stopped.

createServerSocket

protected ServerSocket createServerSocket(int port,
 int backlog,
 @Nullable
 InetAddress whichNic)
                                   throws IOException

Create a new ServerSocket. This default implementation uses the default ServerSocketFactory. Override to use some other mechanism

Parameters:

port - The port.

backlog - The server socket backlog.

whichNic - An InetAddress if binding to a specific network interface. Set to null when configured to bind to all interfaces.

Returns:

The Server Socket.

Throws:

IOException - Any IOException.

stop

public void stop()

Description copied from class: AbstractConnectionFactory

Stops the server.

Specified by:

stop in interface Lifecycle

Specified by:

stop in interface ManageableLifecycle

Overrides:

stop in class AbstractConnectionFactory

getServerSocket

protected ServerSocket getServerSocket()

Returns:

the serverSocket

getTcpSocketFactorySupport

protected TcpSocketFactorySupport getTcpSocketFactorySupport()
