發行項

用於受控制序列的常數 bucket 迭代器類型。

typedef T5 const_local_iterator;

備註

型別描述可以當做常數正向 iterator Base Bucket 的物件。它會說明此做為由實作環境決定型別 T5的同義字。

範例

// std_tr1__unordered_map__unordered_map_const_local_iterator.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 bucket containing 'a' 
    Mymap::const_local_iterator lit = c1.begin(c1.bucket('a')); 
    std::cout << " [" << lit->first << ", " << lit->second << "]"; 
 
    return (0); 
    }
