template<typename ReturnT>

virtual Ptr 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::LanczosFunction2< ReturnT >, lsst.afw.math::Chebyshev1Function2< ReturnT >, lsst.afw.math::PolynomialFunction2< ReturnT >, lsst.afw.math::NullFunction2< ReturnT >, lsst.afw.math::DoubleGaussianFunction2< ReturnT >, lsst.afw.math::GaussianFunction2< ReturnT >, lsst.afw.math::IntegerDeltaFunction2< ReturnT >, lsst::meas::algorithms::ShapeletSpatialFunction, and lsst::meas::algorithms::ShapeletKernelFunction.

template<typename ReturnT>

virtual std::vector<double> lsst.afw.math::Function2< ReturnT >::getDFuncDParameters	(	double	,
		double
	)		const

inlinevirtual

Return the derivative of the Function with respect to its parameters

Reimplemented in lsst.afw.math::PolynomialFunction2< ReturnT >, and lsst.afw.math::BasePolynomialFunction2< ReturnT >.
