Re: [Quantlib-dev] Piecewise Yield curve test

[Luigi B. <lui...@gm...>]

Hi,
    while it's possible that someone on this list can answer, this is
the mailing list for the C++ version.  You might have better luck
asking on the JQuantLib forums or mailing lists.  The links for both
are available at <http://www.jquantlib.org/index.php/Contact_us>.
