受控序列的反转迭代器的类型。

    typedef T3 reverse_iterator;

备注

类型描述可以为控制序列作为反转迭代器的未指定的 T3 类型对象。

示例

// cliext_hash_map_reverse_iterator.cpp 
// compile with: /clr 
#include <cliext/hash_map> 
 
typedef cliext::hash_map<wchar_t, int> Myhash_map; 
int main() 
    { 
    Myhash_map c1; 
    c1.insert(Myhash_map::make_value(L'a', 1)); 
    c1.insert(Myhash_map::make_value(L'b', 2)); 
    c1.insert(Myhash_map::make_value(L'c', 3)); 
 
// display contents " [a 1] [b 2] [c 3]" reversed 
    Myhash_map::reverse_iterator rit = c1.rbegin(); 
    for (; rit != c1.rend(); ++rit) 
        System::Console::Write(" [{0} {1}]", rit->first, rit->second); 
    System::Console::WriteLine(); 
    return (0); 
    }
