clone()

template<typename ReturnT >

virtual std::shared_ptr< Function2< ReturnT > > lsst::afw::math::Function2< ReturnT >::clone ( ) const

pure virtual

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

Implemented in lsst::afw::math::NullFunction2< ReturnT >, lsst::afw::math::IntegerDeltaFunction2< ReturnT >, lsst::afw::math::GaussianFunction2< ReturnT >, lsst::afw::math::DoubleGaussianFunction2< ReturnT >, lsst::afw::math::PolynomialFunction2< ReturnT >, lsst::afw::math::Chebyshev1Function2< ReturnT >, and lsst::afw::math::LanczosFunction2< ReturnT >.

staticinherited

Dynamically cast a shared_ptr.

Dynamically cast a shared pointer and raise on failure.

You must provide an explicit template instantiation in the .cc file for each class that inherits from PersistableFacade. Designed to work around RTTI issues on macOS with hidden symbols;
