Detailed Description

Defines an interface and common methods for sending simple messages (see simple_message). This interface makes a bare minimum of assumptions:

1. The connection is capable of sending raw bytes (encapsulated within a simple message)

2. The data connection has an explicit connect that establishes the connection (and an associated disconnect method). NOTE: For data connections that are connectionless, such as UDP, the connection method can be a NULL operation.

Member Function Documentation

virtual bool industrial::smpl_msg_connection::SmplMsgConnection::isConnected ( ) [pure virtual]

return connection status

Returns:: true if connected

Implemented in industrial::simple_socket::SimpleSocket.

virtual bool industrial::smpl_msg_connection::SmplMsgConnection::makeConnect ( ) [pure virtual]

connects to the remote host

Returns:: true on success, false otherwise

Implemented in industrial::tcp_client::TcpClient, industrial::tcp_server::TcpServer, industrial::udp_client::UdpClient, and industrial::udp_server::UdpServer.

virtual bool industrial::smpl_msg_connection::SmplMsgConnection::receiveBytes	(	industrial::byte_array::ByteArray &	buffer,
		industrial::shared_types::shared_int	num_bytes
	)		`[private, pure virtual]`

Method used by receive message interface method. This should be overridden for the specific connection type.

Parameters:

data	to receive.
size	(in bytes) of data to receive

Returns:: true if successful

Implemented in industrial::simple_socket::SimpleSocket, and TestServer.

bool industrial::smpl_msg_connection::SmplMsgConnection::receiveMsg ( industrial::simple_message::SimpleMessage & message ) [virtual]

Receives a message using the data connection.

Parameters:

populated with received message

Returns:: true if successful

Definition at line 79 of file smpl_msg_connection.cpp.

bool industrial::smpl_msg_connection::SmplMsgConnection::sendAndReceiveMsg	(	industrial::simple_message::SimpleMessage &	send,
		industrial::simple_message::SimpleMessage &	recv,
		bool	verbose = `false`
	)

Performs a complete send and receive. This is helpful when sending a message that requires and explicit reply.

Parameters:

message	to send
populated	with received message
verbosity	level of low level logging

Returns:: true if successful

Definition at line 127 of file smpl_msg_connection.cpp.

virtual bool industrial::smpl_msg_connection::SmplMsgConnection::sendBytes ( industrial::byte_array::ByteArray & buffer ) [private, pure virtual]

Method used by send message interface method. This should be overridden for the specific connection type.

Parameters:

data to send.

Returns:: true if successful

Implemented in TestClient.

bool industrial::smpl_msg_connection::SmplMsgConnection::sendMsg ( industrial::simple_message::SimpleMessage & message ) [virtual]

Sends a message using the data connection.

Parameters:

message to send

Returns:: true if successful

Definition at line 56 of file smpl_msg_connection.cpp.
