Detailed Description

template<typename GFS, typename V, int diffOrder = 0>
class Dune::PDELab::DiscreteGridViewFunction< GFS, V, diffOrder >

A discrete function defined over a GridFunctionSpace.

This class models the GridViewFunction concept of dune-functions. It represents a global function. The user can obtain a GridViewFunction::LocalFunction via localfunction(globalfunction) and use this to evaluate in local coordinates.

Note

it is going to replace the old interfaces based on GridFunctionInterface and FunctionInterface

Template Parameters

GFS	the GridFunctionSpace this function is defined on. GFS yields information on the particular basis.
V	the storage container for the coefficients of the discrete function.

Get local function of wrapped function.

This is free function will be found by ADL.

Notice that the returned LocalFunction can only be used after it has been bound to a proper local context.
