Detailed Description

template<typename T>
class Arcane::SharedArray2< T >

Shared 2D data vector with reference semantics.

SharedArray2<int> a1(5,7);
SharedArray2<int> a2;
a2 = a1;
a1[3][6] = 1;
a2[1][2] = 2;

In the previous example, a1 and a2 refer to the same memory area, so a1[3][6] will have the same value as a2[1][2].

To have a vector that copies elements upon assignment, you must use the UniqueArray2 class.

For more information, refer to SharedArray.
