Declared in <bslstl_unorderedmultiset.h>
Return an iterator providing modifiable access to the first value_type object (in the sequence of value_type objects) maintained by this unordered multiset, or the end iterator if this unordered multiset is empty.
unordered_multiset<KEY, HASH, EQUAL, ALLOCATOR>::iterator
begin() noexcept;Return an iterator to the first element of this unordered multiset.
unordered_multiset<KEY, HASH, EQUAL, ALLOCATOR>::const_iterator
begin() const noexcept;Return a local iterator providing modifiable access to the first value_type object in the sequence of value_type objects of the bucket having the specified index, in the array of buckets maintained by this unordered multiset, or the end(index) otherwise.
unordered_multiset<KEY, HASH, EQUAL, ALLOCATOR>::local_iterator
begin(size_type index);Return a local iterator to the first element in the bucket at index.
unordered_multiset<KEY, HASH, EQUAL, ALLOCATOR>::const_local_iterator
begin(size_type index) const;
