InitModel()

bool InitModel ( void  )

overridevirtual

Initializes the instance.

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

Returns

true if the execution succeeded.

Reimplemented from FGModel.

Definition at line 95 of file FGInputSocket.cpp.

{
  if (FGInputType::InitModel()) {
    delete socket;
    socket = new FGfdmSocket(SockPort, SockProtocol);
 
    if (socket == 0) return false;
    if (!socket->GetConnectStatus()) return false;
 
    return true;
  }
 
  return false;
}

Here is the call graph for this function:

Load()

bool Load ( Element *  el )

overridevirtual

Init the input directives from an XML file.

Parameters

element

XML Element that is pointing to the input directives

Reimplemented from FGModel.

Reimplemented in FGUDPInputSocket.

Definition at line 74 of file FGInputSocket.cpp.

{
  if (!FGInputType::Load(el))
    return false;
 
  SockPort = atoi(el->GetAttributeValue("port").c_str());
 
  if (SockPort == 0) {
    cerr << endl << "No port assigned in input element" << endl;
    return false;
  }
 
  string action = el->GetAttributeValue("action");
  if (to_upper(action) == "BLOCKING_INPUT")
    BlockingInput = true;
