Detailed Description

template<typename GUM_SCALAR>
class gum::BIFReader< GUM_SCALAR >

Definition of templatized reader of BIF files for Bayesian networks.

how to use it :

// OPTIONAL LISTENER CLASS
class aSimpleListener : public gum::Listener {
public:
  void whenLoading(const void *buffer,int percent) {
  // percent goes from 0 to 100 (whenLoading is called at most once for each
integer between 0 and 100
    // percent=200 recieved when End Of File.
 }
};
// END OF OPTIONAL LISTENER

 gum::BayesNet<double> bn;

 try {
  gum::BIFReader<double> reader(&bn,std::string(args[1]));

  // OPTIONAL SECTION
  aSimpleListener l;
  GUM_CONNECT(reader.scanner(),onLoad,l,aSimpleListener::whenLoading);
  // END OF OPTIONNAL SECTION

  if (reader.proceed()==0) {
   std::cerr<<"Well done !"<<std::endl;
  } else {
   reader.showElegantErrorsAndWarnings();
   reader.showErrorCounts();
  }
 } catch (gum::IOError& e) {GUM_SHOWERROR(e);}

  return 0;
