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, end, and grainsize.

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 part, the old range r has the first part. Unspecified if end()<begin() or !is_divisible().

template<typename Value>

|

| tbb::blocked_range< Value >::blocked_range | ( | blocked_range< Value > & | r, | | | | proportional_split & | proportion | | | ) | | |

| inline |

Split range.

The new Range *this has the second part split according to specified proportion, the old range r has the first part. 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().

Referenced by tbb::blocked_range2d< RowValue, ColValue >::is_divisible(), and tbb::blocked_range3d< PageValue, RowValue, ColValue >::is_divisible().

template<typename Value>

|

| size_type tbb::blocked_range< Value >::size | ( | | ) | const |

| inline |

Size of the range.

Unspecified if end()<begin().

Referenced by tbb::blocked_range< I >::is_divisible().
