IteratorsΒΆ

Template classes concurrent_set and concurrent_multiset support forward iterators. Reverse iterators are not supported: reverse_iterator and const_reverse_iterator member types, rbegin() and rend() methods are not available.

Concurrent operations (count, insert, find, etc.) do not invalidate any existing iterators that point into the set. Erasure (unsafe_erase, unsafe_extract) does not invalidate iterators other than those pointing to erased elements.

Note that an iterator obtained via begin() will no longer point to the first element in the set if insert inserts an item before it.

The following table provides information on the members of concurrent_set and concurrent_multiset.

Member, Description

iterator begin()

Returns: iterator pointing to the first element in the set.

const_iterator begin() const

Returns: const_iterator pointing to the first element in the set.

const_iterator cbegin() const

Returns: const_iterator pointing to the first element in the set.

iterator end()

Returns: iterator pointing to the immediately past last element in the set.

const_iterator end() const

Returns: const_iterator pointing to the immediately past last element in the set.

const_iterator cend() const

Returns: const_iterator pointing to the immediately past last element in the set.
