Detailed Description

template<int RankValue>
class Arcane::ArrayStridesBase< RankValue >

Class to maintain the stride in each dimension.

The stride for a dimension is the memory distance between two elements of the array for that dimension. Generally, the stride is equal to the number of elements in the dimension unless padding is used, for example, to align certain dimensions.
