hash_multiset::emplace
Inserts an element constructed in place into a hash_multiset.
template<class ValTy>
iterator insert(
ValTy&& _Val
);
Parameters
Parameter |
Description |
_Val |
The value of an element to be inserted into the hash_multiset Class unless the hash_multiset already contains that element or, more generally, an element whose key is equivalently ordered. |
Return Value
The emplace member function returns an iterator that points to the position where the new element was inserted.
Remarks
In Visual C++ .NET 2003, members of the <hash_map> and <hash_set> header files are no longer in the std namespace, but rather have been moved into the stdext namespace. See The stdext Namespace for more information.
Example
// hash_multiset_emplace.cpp
// compile with: /EHsc
#include <hash_set>
#include <iostream>
#include <string>
int main( )
{
using namespace std;
using namespace stdext;
hash_multiset<string> hms3;
string str1("a");
hms3.emplace(move(str1));
cout << "After the emplace insertion, hms3 contains "
<< *hms3.begin() << "." << endl;
}
After the emplace insertion, hms3 contains a.
Requirements
