optional< variant< std::vector<double>, triplet<double>, pair<double>, double> >

The size of fusion::vector is variable. The optionals are never empty.

 

In 1 possible instance of this fusion vector, we have these runtime values

{

  5.5, 10.1, 15.7, 30.9      //std::vector<double>  v1

  5:15:5                          // triplet<int> range from 5 to 10 incrementing with 4

  5.4                              // double,   value fixed at 5.4

}

 

I wish to generate at runtime the following code (not always 3-deep for loops, the 3 would be known at compile time, but the bounds of the indices in the for loops are only known at runtime)

 

for (size_t index1=0; index1< v1.size(); ++index1) {

  for (int index2=5; index2<=15; index2+=5) {

    for (double index3=5.4; index3<=5.4; ++index3) {

      // some code

    }

  }

}

 

is this possible?

 

regards,
