Detailed Description

template<class DataType>
class Arcane::Array2View< DataType >

Mutable view for a 2D array.

Like any view, an instance of this class is only valid as long as the container it originates from does not change its number of elements.

Definition at line 37 of file arccore/src/base/arccore/base/Array2View.h.
