Constructor & Destructor Documentation

FileReader::FileReader (  string  nfilename, MessageController *  ptr )

Constructor. Parameters: nfilename  The filename of the file to be processed. ptr  A reference to the MessageController. Definition at line 143 of file FileReader.cpp. References filename, filereadthread, filereadthread_run, flexRead, and msgcontroller.

FileReader::~FileReader (   )

Definition at line 160 of file FileReader.cpp. References filereadthread, and filereadthread_run.

Member Function Documentation

bool FileReader::sendMessage (  shared_ptr< vector< shared_ptr< string > > >  messagebody  )  [virtual]

Method used by the MessageController to send messages to Traplas. Obviously, when reading a file no messages can be sent. Therefore this method always returns false. Parameters: messagebody  A reference to the message. Returns: false. The filereader has no connection to Traplas so it can't send the message anywhere. Implements Comm. Definition at line 168 of file FileReader.cpp.

Friends And Related Function Documentation

void* flexRead (  void *  ptr  )  [friend]

Thread to read the input file generated by Traplas containing a simulation. This thread uses flex to process the input file. Entire messages are matched, then these messages are sent to the MessageController. When a line in the inputfile is not recognised, a message is send to cout containing the linenumber and the unrecognised message itself. Definition at line 89 of file FileReader.cpp. Referenced by FileReader().

void* readFile (  void *  ptr  )  [friend]

Thread to read the input file generated by Traplas containing a simulation. This thread uses a simple way the read a file, it offers no checks whatsoever on what it reads. It just reads lines using a getline(), then it makes token using a space(" ") as delimiter. Then it sends the messages to the MessageController. Definition at line 100 of file FileReader.cpp.

bool send (  char *  line  )  [friend]

Helper function for yylex() to send messages to the MessageController. It sends the message to the MessageController. Definition at line 73 of file FileReader.cpp.
