Defines a udp inbound Channel Adapter for receiving incoming udp packets. The number of threads that will be used for socket/channel handling. Only applies if an external task-executor is NOT being used. When using an external task executor, its configuration specifies the number of threads. Specifies a specific Executor to be used for socket handling. If not supplied, an internal pooled executor will be used (See pool-size). Needed on some platforms that require the use of specific task executors such as a WorkManagerTaskExecutor. If a (synchronous) downstream exception is thrown and an "error-channel" is specified, the MessagingException will be sent to this channel. Otherwise, any such exception will simply be logged by the channel adapter. Whether or not to do a DNS reverse-lookup on the remote ip address to insert the host name into the message headers (ip_hostName). Default "true". Defines an outbound UDP packet-sending Channel Adapter. Specifies a specific Executor to be used for handling acknowledgments in the UDP adapter. If not supplied, an internal pooled executor will be used. Needed on some platforms that require the use of specific task executors such as a WorkManagerTaskExecutor. Specifies the order for invocation when this endpoint is connected as a subscriber to a SubscribableChannel. A connection factory is needed by an inbound adapter. If the connection factory has a type 'server', the factory is 'owned' by this adapter. If it has a type 'client', it is owned by an outbound channel adapter and this adapter will receive any incoming messages on the connection created by the outbound adapter. If a (synchronous) downstream exception is thrown and an "error-channel" is specified, the MessagingException will be sent to this channel. Otherwise, any such exception will simply be logged by the channel adapter. A connection factory is needed by an outbound adapter. If the connection factory has a type 'client', the factory is 'owned' by this adapter. If it has a type 'server', it is owned by an inbound channel adapter and this adapter will attempt to correlate messages to the connection on which an original inbound message was received. Specifies the order for invocation when this endpoint is connected as a subscriber to a SubscribableChannel. A connection factory is needed by an inbound adapter. The connection factory must be of type 'server'. If a (synchronous) downstream exception is thrown and an "error-channel" is specified, the MessagingException will be sent to this channel and the ultimate response of the error flow will be returned as a response by the gateway. If no "error-channel" is specified, any such exception will simply be logged by the gateway. In such a situation, no response is sent to the client. A connection factory is needed by an outbound adapter. The connection factory must be of 'client'. Specifies the order for invocation when this endpoint is connected as a subscriber to a SubscribableChannel. Connection factories can be 'client' or 'server'. Client factories open a connection to a server using a host and port. Server factories listen on a port and create a separate connection for each incoming connection request. The host to which a client connection factory will connect. For client factories, the port to which a client connection factory will connect. For server factories, the port on which the factory will listen for incoming connections. If true, the factory will use java.nio.channel.SocketChannel for communication; for a large number of connections on the server side, this can provide better performance and may use fewer threads. If true, instructs the factory to use direct buffers if possible; only applies if using-nio is true. Refer to ByteBuffer javadocs for more information. If true, a new connection will be created for each use. For inbound adapters where there is no outbound adapter sharing the factory, the connection will be closed after a message is received. For outbound adapters where there is no inbound adapter sharing the factory, or for inbound adapters where an outbound adapter shares the factory, the connection will be closed after so-timeout milliseconds. For outbound adapters where an inbound adapter shares the factory, the connection will be closed after a response is received. A Serializer that converts message payloads to/from output streams/input streams associated with the connection. Default is ByteArrayCrLfSerializer. Serializer and Deserializer would normally be the same but this is not required. A Deserializer that converts message payloads to/from output streams/input streams associated with the connection. Default is ByteArrayCrLfSerializer. Serializer and Deserializer would normally be the same but this is not required. On a multi-homed system, specifies the ip address of the network interface used to communicate. For inbound adapters and gateways, specifies the interface used to listen for incoming connections. If omitted, the endpoint will listen on all available adapters. For the UDP multicast outbound adapter specifies the interface to which multicast packets will be sent. For UDP unicast and multicast adapters, specifies which interface to which the acknowledgment socket will be bound. Does not apply to TCP outbound adapters and gateways. The number of threads that will be used for socket/channel handling. Only applies if an external task-executor is NOT being used. When using an external task executor, its configuration specifies the number of threads. Whether or not to do a DNS reverse-lookup on the remote ip address to insert the host name into the message headers (ip_connectionId, ip_hostName). Default "true". Common configuration for UDP-based adapters. On a multi-homed system, specifies the ip address of the network interface used to communicate. For inbound adapters and gateways, specifies the interface used to listen for incoming connections. If omitted, the endpoint will listen on all available adapters. For the UDP multicast outbound adapter specifies the interface to which multicast packets will be sent. For UDP unicast and multicast adapters, specifies which interface to which the acknowledgment socket will be bound. Does not apply to TCP outbound adapters and gateways.
