public class TcpInboundGateway
extends MessagingGatewaySupport
implements TcpListener, TcpSender, ClientModeCapable

Inbound Gateway using a server connection factory - threading is controlled by the factory. For java.net connections, each socket can process only one message at a time. For java.nio connections, messages may be multiplexed but the client will need to provide correlation logic. If the client is a TcpOutboundGateway multiplexing is not used, but multiple concurrent connections can be used if the connection factory uses single-use connections. For true asynchronous bi-directional communication, a pair of inbound / outbound channel adapters should be used.

Method Detail

onMessage

public boolean onMessage(Message<?> message)

Description copied from interface: TcpListener

Called by a TCPConnection when a new message arrives.

Specified by:

onMessage in interface TcpListener

Parameters:

message - The message.

Returns:

true if the message was intercepted

isListening

public boolean isListening()

Returns:

true if the associated connection factory is listening.

setConnectionFactory

public void setConnectionFactory(AbstractConnectionFactory connectionFactory)

Must be AbstractClientConnectionFactory or AbstractServerConnectionFactory.

Parameters:

connectionFactory - the Connection Factory

addNewConnection

public void addNewConnection(TcpConnection connection)

Description copied from interface: TcpSender

When we are using sockets owned by a TcpListener, this method is called each time a new connection is made.

Specified by:

addNewConnection in interface TcpSender

Parameters:

connection - The connection.

removeDeadConnection

public void removeDeadConnection(TcpConnection connection)

Description copied from interface: TcpSender

When we are using sockets owned by a TcpListener, this method is called each time a connection is closed.

Specified by:

removeDeadConnection in interface TcpSender

Parameters:

connection - The connection.

getComponentType
