No, it's not nice. But unfortunately there's no such method at this
time.

...and it's hard to extract it, too. For one thing, it's not in the
option itself, since the option doesn't contain directly the process for
the underlying (on which its forward value depends.) You should extract
the engine from the instrument, cast it to the correct type, and extract
the stochastic process from it.---assuming that all the inspectors
exist. Then the expected underlying value at maturity has to be
calculated.
It I may make a suggestion, I'd store the required data in your
portfolio together with your instruments. As far as I see, your
component_ member already contains other data besides the
shared_ptr<Instrument>. When you create the instruments (at which point
you know already what each instrument is, and you have its input data at
hand) you might consider getting hold of its cashflows or its underlying
process and add them to the items in component_.
