Detailed Description

template<int n, typename TRing, typename TOwner, typename TAlloc, typename TX>
class DGtal::MPolynomialEvaluatorImpl< n, TRing, TOwner, TAlloc, TX >

Description of template class 'MPolynomialEvaluatorImpl'

Another helper for polynomial evaluation. This template is returned from MPolynomialEvaluator<n, TRing, TAlloc>::operator().

The template parameter TOwner is the type of the "owner" of this template, i.e. either MPolynomialEvaluator<n+1, TRing, TAlloc> or MPolynomialEvaluatorImpl<n+1, TRing, ..., TAlloc>.

This class is a backport from Spielwiese.

MPolyN

template<int n, typename TRing , typename TOwner , typename TAlloc , typename TX >

typedef MPolynomial< n, Ring, Alloc> DGtal::MPolynomialEvaluatorImpl< n, TRing, TOwner, TAlloc, TX >::MPolyN

Type for the multivariate polynomial.

template<typename XX , typename Fun >

void DGtal::MPolynomialEvaluatorImpl< n, TRing, TOwner, TAlloc, TX >::evaluate ( XX &  res, const Fun &  evalfun  ) const

This will be called from a child (i.e. a class of type MPolynomialEvaluatorImpl<n-1, Ring, MPolynomialEvaluator<n,Ring,Owner,Alloc,X>, Alloc, X>) to trigger evaluation.

Definition at line 261 of file MPolynomial.h.

    {
        // We have to pass evaluation on to our owner, but give a new
        // functor which now evaluates polynomials of type poly<n, T>.
      myOwner.evaluate( res, EvalFun< XX, Fun >( *this, evalfun ) );

operator MPolyNM1()

template<int n, typename TRing , typename TOwner , typename TAlloc , typename TX >

DGtal::MPolynomialEvaluatorImpl< n, TRing, TOwner, TAlloc, TX >::operator MPolyNM1 ( ) const

Allows casting to poly<n-1, S>.
