Constructor Detail

TcpNioServerConnectionFactory

public TcpNioServerConnectionFactory(int port)

Listens for incoming connections on the port.

Parameters:

port - The port.

Method Detail

getComponentType

public java.lang.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 java.net.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.

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.

doAccept

protected void doAccept(java.nio.channels.Selector selector,
                        java.nio.channels.ServerSocketChannel server,
                        long now)
                 throws java.io.IOException

Overrides:

doAccept in class AbstractConnectionFactory

Parameters:

selector - The selector.

server - The server socket channel.

now - The current time.

Throws:

java.io.IOException - Any IOException.

stop

public void stop()

Description copied from class: AbstractConnectionFactory

Stops the server.

Specified by:

stop in interface org.springframework.context.Lifecycle

Overrides:

stop in class AbstractConnectionFactory

setUsingDirectBuffers

public void setUsingDirectBuffers(boolean usingDirectBuffers)

setTcpNioConnectionSupport

public void setTcpNioConnectionSupport(TcpNioConnectionSupport tcpNioSupport)

getServerChannel

protected java.nio.channels.ServerSocketChannel getServerChannel()

Returns:

the serverChannel

isUsingDirectBuffers

protected boolean isUsingDirectBuffers()

Returns:

the usingDirectBuffers

getConnections

protected java.util.Map<java.nio.channels.SocketChannel,TcpNioConnection> getConnections()

Returns:

the connections
