template<typename InElementType, typename InSizeType> class TStridedView

Remarks

TStridedView is similar to TArrayView, but allows flexible byte stride between elements. Stride must be positive and a multiple of the element alignment. Stride can be zero to duplicate the same element over the whole range.

Example usage:

struct FMyStruct { uint32 SomeData; FVector Position; };

FVector ComputeMean(TStridedView Positions) { return Algo::Accumulate(Positions, FVector(0.0f)) / Positions.Num(); }

FVector ComputeMeanPosition(TArrayView Structs) { return ComputeMean(MakeStridedView(Structs, &FMyStruct::Position)) }

See StridedViewTest.cpp for more examples. Pointer with extent and a stride, similar to TArrayView. Designed to allow functions to take pointers to arbitrarily structured data.
