unordered_map::end
Designates the end of the controlled sequence.
iterator end();
const_iterator end() const;
local_iterator end(size_type nbucket);
const_local_iterator end(size_type nbucket) const;
Parameters
Parameter |
Description |
nbucket |
The bucket number. |
Remarks
The first two member functions return a forward iterator that points just beyond the end of the sequence. The last two member functions return a forward iterator that points just beyond the end of bucket nbucket.
Example
Code
// std_tr1__unordered_map__unordered_map_end.cpp
// compile with: /EHsc
#include <unordered_map>
#include <iostream>
typedef std::unordered_map<char, int> Mymap;
int main()
{
Mymap c1;
c1.insert(Mymap::value_type('a', 1));
c1.insert(Mymap::value_type('b', 2));
c1.insert(Mymap::value_type('c', 3));
// display contents " [c 3] [b 2] [a 1]"
for (Mymap::const_iterator it = c1.begin();
it != c1.end(); ++it)
std::cout << " [" << it->first << ", " << it->second << "]";
std::cout << std::endl;
// inspect last two items " [a 1] [b 2]"
Mymap::iterator it2 = c1.end();
--it2;
std::cout << " [" << it2->first << ", " << it2->second << "]";
--it2;
std::cout << " [" << it2->first << ", " << it2->second << "]";
std::cout << std::endl;
// inspect bucket containing 'a'
Mymap::const_local_iterator lit = c1.end(c1.bucket('a'));
--lit;
std::cout << " [" << lit->first << ", " << lit->second << "]";
return (0);
}
Output
[c, 3] [b, 2] [a, 1]
[a, 1] [b, 2]
[a, 1]
