NAME
std::unordered_multiset<Key,Hash,KeyEqual,Allocator>::merge - std::unordered_multiset<Key,Hash,KeyEqual,Allocator>::merge
Synopsis
template<class H2, class P2> (1) (since C++17)
void merge(std::unordered_set<Key, H2, P2, Allocator>& source);
template<class H2, class P2> (2) (since C++17)
void merge(std::unordered_set<Key, H2, P2, Allocator>&& source);
template<class H2, class P2> (3) (since C++17)
void merge(std::unordered_multiset<Key, H2, P2, Allocator>& source);
template<class H2, class P2> (4) (since C++17)
void merge(std::unordered_multiset<Key, H2, P2, Allocator>&& source);
Attempts to extract ("splice") each element in source and insert it into *this using the hash function and key equality predicate of *this.
No elements are copied or moved, only the internal pointers of the container nodes are repointed. All pointers and references to the transferred elements remain valid, but now refer into *this, not into source. Iterators referring to the transferred elements and all iterators referring to *this are invalidated.
The behavior is undefined if get_allocator() != source.get_allocator().
Parameters
source - compatible container to transfer the nodes from
Return value
(none)
Complexity
Average case O(N), worst case O(N*size()+N), where N is source.size()
