Detailed Description

template<class DataType>
class Arcane::MachineShMemWinVariableArrayT< DataType >

Class allowing access to the 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 array variables without support.

If the size of the variable changes while an object of this type is used, it is necessary to call the updateVariable() method.
