C++ (Cpp) DataBufferTrivial Examples

Example #1

int main(int argc, char* argv[])
{
  SignalScalerComponent mod("test");
  mod.registerPorts();

  map<string, int> iTypes,oTypes;
  iTypes["input1"] = TypeInfo< complex<float> >::identifier;
  mod.calculateOutputTypes(iTypes,oTypes);

  DataBufferTrivial< complex<float> > in;
  DataBufferTrivial< complex<float> > out;

  DataSet< complex<float> >* iSet = NULL;
  int num = 1000000;
  in.getWriteData(iSet, num);
  for(int i=0;i<num;i++)
    iSet->data[i] = complex<float>(i,i);
  in.releaseWriteData(iSet);

  mod.setBuffers(&in,&out);
