[Quantlib-users] Possible Time Series Bug

[marco\.tarenghi\@libero\.it <mar...@li...>]

Hi all,
I think I've found a bug in the TimeSeries class.
There it is implemented the [] operator in two different ways, I think th=
e second one is wrong: more in detail, according to me the operator retur=
ning a reference contains an error in the "if" condition

T& operator[](const Date& d) {
    if (values_.find(d) !=3D values_.end())
        values_[d] =3D Null<T>();
        return values_[d];
    }
}

it should be "=3D=3D" and not "!=3D", otherwise in the case it finds the =
date it returns a Null<T> value.
Probably it has been mis-specified because it replicates the implementati=
on of the alternative [] operator, but in that case the output is differe=
nt and the operator works fine.

By the way, if I instantiate a TimeSeries object and then I use the [] op=
erator, how does the object know which is implementation to choose?

Thanks,
