Detailed Description

template<class ItemType, class DataType, class Extents>
class Arcane::MachineShMemWinMeshVectorMDVariableT< ItemType, DataType, Extents >

Class allowing access to shared elements of the variable in shared memory.

It is necessary that this variable be allocated in shared memory with the property "IVariable::PInShMem".

This class works for vector mesh variables with a maximum dimension of 2.

If the mesh and/or the variable size changes when an object of this type is used, it is necessary to call the updateVariable() method.
