HullWhite.discount(...) Is this exposed to Python SWIG?

[newbie73]

While looking through the Bermudan Swaption pricing example, I tried to access the discount(t) method of the HullWhite object defined in onefactormodel.hpp.  This method is not recognized and a dir(...) on the HullWhite object revealed that this method was not visible.

Any help with this?  Which models/term structures can be used as they are in the documentation?
