Receives a message using the data connection. More... | |
virtual bool | receiveMsg (industrial::simple_message::SimpleMessage &message, industrial::shared_types::shared_int timeout_ms) |
Receives a message using the data connection with a timeout. More... | |
bool | 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. More... | |

Protected Member Functions inherited from industrial::simple_socket::SimpleSocket | |
__attribute__ ((deprecated("Please use: logSocketError(const char* msg, const int rc, const int error_no)"))) void logSocketError(const char *msg | |
Logs message to error log and reports associated socket system error. More... | |
int | getSockHandle () const |
void | logSocketError (const char *msg, const int rc, const int error_no) |
Logs message to error log and reports associated socket system error. More... | |
bool | receiveBytes (industrial::byte_array::ByteArray &buffer, industrial::shared_types::shared_int num_bytes, industrial::shared_types::shared_int timeout_ms) |
Method used by receive message interface method. This should be overridden for the specific connection type. More... | |
bool | sendBytes (industrial::byte_array::ByteArray &buffer) |
Method used by send message interface method. This should be overridden for the specific connection type. More... | |
virtual void | setConnected (bool connected) |
void | setSockHandle (int sock_handle_) |
Protected Attributes | |
int | srvr_handle_ |
server handle. Every time a connection is made, the class generates a new handle for sending/receiving. The server handle is saved off to a separate variable so that recoving a lost connection is possible. More... | |
Protected Attributes inherited from industrial::simple_socket::SimpleSocket | |
char | buffer_ [MAX_BUFFER_SIZE+1] |
internal data buffer for receiving More... | |
bool | connected_ |
flag indicating socket connection status More... | |

socket handle for sending/receiving data More... | |
sockaddr_in | sockaddr_ |
address/port of remote socket More... | |
