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().

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().
