	Global coordinates of the EntitySet.
using	Range = std::conditional_t< std::is_same_v< R, void >, RangeType_t< SubTree, Coefficient >, R >
	Range type of this DiscreteFunction. If R=void deduce the Range automatically, using RangeType_t.

Detailed Description

template<class Coeff, class GB, class TreePath, class R>
class AMDiS::DiscreteFunction< Coeff const, GB, TreePath, R >

A Const DiscreteFunction.

Member Enumeration Documentation

anonymous enum

anonymous enum

Mark this class to not directly implement the derivativeOf function so that the DerivativeGridFunction can be used.

Constructor & Destructor Documentation

DiscreteFunction()

DiscreteFunction ( C &&  coefficients, B &&  basis, Path...  path  )

inline

Wrap or move or share the coefficients vector and basis reference or rvalue, respectively, into shared_ptr.

Parameters

coefficients	The vector can be passed either as const ref or as shared_ptr. If passed as rvalue-ref it is moved into a new shared_ptr.
basis	A global basis passed either as const ref or shared_ptr.
path...	The indices of a tree-path or the tree-path directly.
