Detailed Description

Implements the output to a socket.

This class outputs data to a socket according to the JSBSim format. It can be inherited as a generic class that provides services for socket outputs. For instance FGOutputFG inherits FGOutputSocket for the socket management but outputs data with a format different than FGOutputSocket.

Member Function Documentation

◆ InitModel()

bool InitModel ( void  )
virtual

Initializes the instance.

This method basically opens the socket to which outputs will be directed.

Returns
true if the execution succeeded.

Reimplemented from FGOutputType.

Definition at line 131 of file FGOutputSocket.cpp.

132 {
133  if (FGOutputType::InitModel()) {
134  delete socket;
135  socket = new FGfdmSocket(SockName, SockPort, SockProtocol);

140  PrintHeaders();
141 
142  return true;
143  }
144 
145  return false;
146 }
virtual bool InitModel(void)
Init the output model according to its configitation.
+ Here is the call graph for this function:

◆ Load()

bool Load ( Element el)
virtual

Init the output directives from an XML file.

Parameters
elementXML Element that is pointing to the output directives

Reimplemented from FGOutputType.

Definition at line 117 of file FGOutputSocket.cpp.

118 {
119  if (!FGOutputType::Load(el))
120  return false;
121 
122  SetOutputName(el->GetAttributeValue("name") + ":" +
123  el->GetAttributeValue("protocol") + "/" +
124  el->GetAttributeValue("port"));
125 
126  return true;
127 }
virtual bool Load(Element *el)
Init the output directives from an XML file (implement the FGModel interface).
virtual void SetOutputName(const std::string &name)
Overwrites the name identifier under which the output will be logged.
+ Here is the call graph for this function:

◆ SetOutputName()

void SetOutputName ( const std::string &  name)
virtual

Overwrites the name identifier under which the output will be logged.

This method is taken into account if it is called before FGFDMExec::RunIC() otherwise it is ignored until the next call to SetStartNewOutput().

Parameters
namenew name in the form "hostname:port/proto" hostname could be an ip, port a numerical value and proto should be UDP or TCP (the default if omitted)

Reimplemented from FGOutputType.

Definition at line 85 of file FGOutputSocket.cpp.

112  SockProtocol = FGfdmSocket::ptTCP;
113 }
+ Here is the caller graph for this function:

◆ SocketStatusOutput()

void SocketStatusOutput ( const std::string &  out_str)

Outputs a status thru the socket.

This method issues a message prepended by the string "<STATUS>" to the socket.

Parameters
out_strstatus message

391 {
392  string asciiData;
393 
394  if (socket == 0) return;
