Class Documentation

template<typename T, size_t R>
class DataView

A multi-dimensional view for MemRef-like and std::vector<T> types.

Note

A forward iterator is implemented in this view for traversing over the entire elements of MemRef types rank-by-rank starting from the last dimension (R-1). For example, The DataView iterator for MemRef<T, 2> starts from index (0, 0) and traverses elements in the following order: (0, 0), …, (0, sizes[1]-1), (1, 0), …, (1, sizes[1]-1), … (sizes[0]-1, sizes[1]-1).

Template Parameters
  • T – The underlying data type

  • R – The Rank (R > 0)
