template<typename ReturnT >
std::shared_ptr<Function2<ReturnT> > lsst::afw::math::DoubleGaussianFunction2< ReturnT >::clone ( ) const
inlineoverridevirtual

Return a pointer to a deep copy of this function.

This function exists instead of a copy constructor so one can obtain a copy of an actual function instead of a useless copy of the base class.

Every non-virtual function must override this method.

Returns
a pointer to a deep copy of the function
