priority_queue::value_comp (STL/CLR)

复制两个元素的排序委托。

    value_compare^ value_comp();

备注

成员函数返回该排序的委托用于对控件序列。 用于对两个值进行比较。

示例

// cliext_priority_queue_value_comp.cpp 
// compile with: /clr 
#include <cliext/queue> 
 
typedef cliext::priority_queue<wchar_t> Mypriority_queue; 
int main() 
    { 
    Mypriority_queue c1; 
    Mypriority_queue::value_compare^ vcomp = c1.value_comp(); 
 
    System::Console::WriteLine("compare(L'a', L'a') = {0}", 
        vcomp(L'a', L'a')); 
    System::Console::WriteLine("compare(L'a', L'b') = {0}", 
        vcomp(L'a', L'b')); 
    System::Console::WriteLine("compare(L'b', L'a') = {0}", 
        vcomp(L'b', L'a')); 
    System::Console::WriteLine(); 
 
// test a different ordering rule 
    Mypriority_queue c2 = cliext::greater<wchar_t>(); 
    vcomp = c2.value_comp(); 
 
    System::Console::WriteLine("compare(L'a', L'a') = {0}", 
        vcomp(L'a', L'a')); 
    System::Console::WriteLine("compare(L'a', L'b') = {0}", 
        vcomp(L'a', L'b')); 
    System::Console::WriteLine("compare(L'b', L'a') = {0}", 
        vcomp(L'b', L'a')); 
    return (0); 
    }
