interpolation error

[Grison PG Pierre (External DEXIA-US)]

Hello,

 

Does anyone have an idea why the following code line

 

optionInterpolator_= LinearInterpolation(optionTimes_.begin(),                                                                                         optionTimes_.end(),

                           optionDatesAsReal_.begin());

 

where optionInterpolator_ is declared as

 

LinearInterpolation optionInterpolator_;

 

And inputs are declared as

 

                     mutable std::vector<Date> optionDates_;

                     mutable std::vector<Time> optionTimes_;

 

 

 

triggers the compile error

 

'QuantLib::LinearInterpolation' : no appropriate default constructor available

 

Thanks,

 

Pierre

Hello,
    the line that's giving the problem is not the one where you build
the interpolation, it's the line

LinearInterpolation optionInterpolator_;

where you declare it. As the compiler says, I'm guessing the code that
builds the interpolation is inside the body of a constructor; but
before executing the body, the data members must be initialized.
LinearInterpolation doesn't have a default constructor, so that's not
possible. Instead, you can declare the data member as just:

Interpolation optionInterpolator_;

The above can be default-constructed, and you'll be able to assign to
it a LinearInterpolation anyway.
