Type enables transmission of splitting proportion from partitioners to range objects.
bool is_divisible() const
True if range is divisible into two pieces.
bool empty() const
True if range is empty.
bool empty() const
True if range is empty.
const row_range_type & rows() const
The rows of the iteration space.

blocked_range2d(blocked_range2d &r, split)
static ColValue do_split(blocked_range &r, split)
Auxiliary function used by the splitting constructor.
static const bool is_splittable_in_proportion
Static field to support proportional split.
blocked_range< ColValue > col_range_type
size_type size() const
Size of the range.
bool is_divisible() const
True if range is divisible.
Dummy type that distinguishes splitting constructor from copy constructor.
size_type grainsize() const
The grain size for this range.

void do_split(blocked_range2d &r, Split &split_obj)
std::size_t size_type
Type for size of a range.
blocked_range< RowValue > row_range_type
Type for size of an iteration range.
A 2-dimensional range that models the Range concept.
const col_range_type & cols() const
The columns of the iteration space.
