Types const_range_type and range_type model the Container Range concept. The types differ only in that the bounds for a const_range_type are of type const_iterator, whereas the bounds for a range_type are of type iterator.
|range_type range( size_t grainsize=1 )||
Returns: Range over entire concurrent_vector that permits read-write access.
|const_range_type range( size_t grainsize=1 ) const||
Returns: Range over entire concurrent_vector that permits read-only access.
