## Detailed Description

### template<typename Value>
class tbb::blocked_range< Value >

A range over which to iterate.

## Member Typedef Documentation

template<typename Value>

typedef Value tbb::blocked_range< Value >::const_iterator

Type of a value.

Called a const_iterator for sake of algorithms that need to treat a blocked_range as an STL container.

## Constructor & Destructor Documentation

template<typename Value>

tbb::blocked_range< Value >::blocked_range | ( |  | ) | `[inline]`

Construct range with default-constructed values for begin and end.

Requires that Value have a default constructor.

template<typename Value>

tbb::blocked_range< Value >::blocked_range | ( | blocked_range< Value > & | r,
|  | split |  |
| ) |  |  | `[inline]`

Split range.

The new Range *this has the second half, the old range r has the first half. Unspecified if end()<begin() or !is_divisible().

## Member Function Documentation

template<typename Value>

bool tbb::blocked_range< Value >::is_divisible | ( |  | ) | const`[inline]`

True if range is divisible.

Unspecified if end()<begin().

template<typename Value>

size_type tbb::blocked_range< Value >::size | ( |  | ) | const`[inline]`

Size of the range.

Unspecified if end()<begin().
