Parallel iteration

Member types concurrent_multimap::range_type and concurrent_multimap::const_range_type meet the ContainerRange requirements.

These types differ only in that the bounds for a concurrent_multimap::const_range_type are of type concurrent_multimap::const_iterator, whereas the bounds for a concurrent_multimap::range_type are of type concurrent_multimap::iterator.

range member function

range_type range();

const_range_type range() const;

Returns: a range object representing all elements in the container.
