operator< (multimap) (STL/CLR)

2013-06-07

比比较表更少。

template<typename Key,
    typename Mapped>
    bool operator<(multimap<Key, Mapped>% left,
        multimap<Key, Mapped>% right);

参数

left
比较左侧的容器。
right
比较的正确的容器。

备注

运算符函数返回 true; 否则，为最低的位置 !(right[i] <left[i]) 它还适用 left[i] <right[i]的 i 。否则，它将返回 left->size() <right使用它测试的->size()left 是否在 right 之前进行排序，当两 multimaps 是比较组件的元素。

示例

// cliext_multimap_operator_lt.cpp 
// compile with: /clr 
#include <cliext/map> 
 
typedef cliext::multimap<wchar_t, int> Mymultimap; 
int main() 
    { 
    Mymultimap c1; 
    c1.insert(Mymultimap::make_value(L'a', 1)); 
    c1.insert(Mymultimap::make_value(L'b', 2)); 
    c1.insert(Mymultimap::make_value(L'c', 3)); 
 
// display contents " [a 1] [b 2] [c 3]" 
    for each (Mymultimap::value_type elem in c1) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
 
// assign to a new container 
    Mymultimap c2; 
    c2.insert(Mymultimap::make_value(L'a', 1)); 
    c2.insert(Mymultimap::make_value(L'b', 2)); 
    c2.insert(Mymultimap::make_value(L'd', 4)); 
 
// display contents " [a 1] [b 2] [d 4]" 
    for each (Mymultimap::value_type elem in c2) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
 
    System::Console::WriteLine("[a b c] < [a b c] is {0}", 
        c1 < c1); 
    System::Console::WriteLine("[a b c] < [a b d] is {0}", 
        c1 < c2); 
    return (0); 
    }
