priority_queue::value_comp (STL/CLR)

Copies the ordering delegate for two elements.

    value_compare^ value_comp();

Remarks

The member function returns the ordering delegate used to order the controlled sequence. You use it to compare two values.

Example

// 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); 
    } 
 

compare(L'a', L'a') = False compare(L'a', L'b') = True compare(L'b', L'a') = False compare(L'a', L'a') = False compare(L'a', L'b') = False compare(L'b', L'a') = True
