Name

blocked_range2d Template Class — Template class that represents a recursively divisible, two-dimensional, half-open interval.

Synopsis

#include "tbb/blocked_range2d.h"

template<typename RowValue, typename ColValue>

  class blocked_range2d;

Description

A blocked_range2d<RowValue,ColValue> represents a half-open, two-dimensional range [i0,j0)x[i1,j1). Each axis of the range has its own splitting threshold. The RowValue and ColValue must meet the requirements in Table 3-3. A blocked_range is splittable if either axis is splittable. A blocked_range models the Range Concept.
