Member Function Documentation

InitModel()

bool InitModel ( void  )

virtual

Initializes the instance.

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

Returns

true if the execution succeeded.

Reimplemented from FGInputType.

Definition at line 94 of file FGInputSocket.cpp.

{
  if (FGInputType::InitModel()) {
    delete socket;
    socket = new FGfdmSocket(SockPort);

    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 )

virtual

Init the input directives from an XML file.

Parameters

element

XML Element that is pointing to the input directives

Reimplemented from FGInputType.

Definition at line 77 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;
  }

  return true;
}
