operator< (queue) (STL/CLR)

2015-06-09

队列小于比较。

template<typename Value,
    typename Container>
    bool operator<(queue<Value, Container>% left,
        queue<Value, Container>% right);

参数

left
比较左边的容器。
right
比较右边的容器。

备注

如果运算符函数返回 TRUE，最低位置的i，其中，!(right[i] < left[i]) 是正确的，left[i] < right[i]。否则，返回left->queue::size (STL/CLR)() < right->size()，当2个队列按元素比较时，您可以用它测试left是否在right之前排序。

示例

// cliext_queue_operator_lt.cpp 
// compile with: /clr 
#include <cliext/queue> 
 
typedef cliext::queue<wchar_t> Myqueue; 
int main() 
    { 
    Myqueue c1; 
    c1.push(L'a'); 
    c1.push(L'b'); 
    c1.push(L'c'); 
 
// display contents " a b c" 
    for each (wchar_t elem in c1.get_container()) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// assign to a new container 
    Myqueue c2; 
    c2.push(L'a'); 
    c2.push(L'b'); 
    c2.push(L'd'); 
 
// display contents " a b d" 
    for each (wchar_t elem in c2.get_container()) 
        System::Console::Write(" {0}", elem); 
    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); 
    }
