Detailed Description

template<typename ItemType, typename Accessor>
class Arcane::ItemVariableRealNScalarOutViewT< ItemType, Accessor >

Write view on a mesh scalar variable of type 'RealN'.

This class specializes modifiable views for the reals 'Real2', 'Real3', 'Real2x2' and 'Real3x3'. The specialization ensures that only the entire vector of these real numbers can be modified. For example:

VariableNodeReal3View force_view = ...;
Node node = ...;
 
// OK:
force_view[node] = Real3(x,y,z);
 
// Forbidden:
// force_view[node].x = ...;
