template<typename ReturnT>

virtual Ptr lsst::afw::math::Function1< 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 concrete subclass must override this method.

Returns: a pointer to a deep copy of the function
