The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at hash_map::value_comp (STL/CLR).

Copies the ordering delegate for two element values.

Syntax

value_compare^ value_comp();  

Remarks

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

Example

// cliext_hash_map_value_comp.cpp   
// compile with: /clr   
#include <cliext/hash_map>   
  
typedef cliext::hash_map<wchar_t, int> Myhash_map;   
int main()   
    {   
    Myhash_map c1;   
    Myhash_map::value_compare^ kcomp = c1.value_comp();   
  
    System::Console::WriteLine("compare([L'a', 1], [L'a', 1]) = {0}",   
        kcomp(Myhash_map::make_value(L'a', 1),   
            Myhash_map::make_value(L'a', 1)));   
    System::Console::WriteLine("compare([L'a', 1], [L'b', 2]) = {0}",   
        kcomp(Myhash_map::make_value(L'a', 1),   
            Myhash_map::make_value(L'b', 2)));   
    System::Console::WriteLine("compare([L'b', 2], [L'a', 1]) = {0}",   
        kcomp(Myhash_map::make_value(L'b', 2),   
            Myhash_map::make_value(L'a', 1)));   
    System::Console::WriteLine();   
    return (0);   
    }  
  

compare
([L'a', 1], [L'a', 1]) = True  
compare
([L'a', 1], [L'b', 2]) = True  
compare
([L'b', 2], [L'a', 1]) = False
