unordered_multiset::bucket_size
Gets the size of a bucket
size_type bucket_size(size_type nbucket) const;
Parameters
- nbucket
The bucket number.
Remarks
The member functions returns the size of bucket number nbucket.
Example
// std_tr1__unordered_set__unordered_multiset_bucket_size.cpp
// compile with: /EHsc
#include <unordered_set>
#include <iostream>
typedef std::unordered_multiset<char> Myset;
int main()
{
Myset c1;
c1.insert('a');
c1.insert('b');
c1.insert('c');
// display contents " [c] [b] [a]"
for (Myset::const_iterator it = c1.begin();
it != c1.end(); ++it)
std::cout << " [" << *it << "]";
std::cout << std::endl;
// display buckets for keys
Myset::size_type bs = c1.bucket('a');
std::cout << "bucket('a') == " << bs << std::endl;
std::cout << "bucket_size(" << bs << ") == " << c1.bucket_size(bs)
<< std::endl;
return (0);
}
[c] [b] [a]
bucket('a') == 7
bucket_size(7) == 1
