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 not2 (STL/CLR).

Generates a binary_negate for a functor.

Syntax

template<typename Fun>  
    binary_negate<Fun> not2(Fun% functor);

Template Parameters

Fun
The type of the functor.

Function Parameters

functor
The functor to wrap.

Remarks

The template function returns binary_negate (STL/CLR)<``Fun``>(functor). You use it as a convenient way to wrap a two-argument functor in a functor that delivers its logical NOT.

Example

// cliext_not2.cpp   
// compile with: /clr   
#include <cliext/algorithm>   
#include <cliext/functional>   
#include <cliext/vector>   
  
typedef cliext::vector<int> Myvector;   
int main()   
    {   
    Myvector c1;   
    c1.push_back(4);   
    c1.push_back(3);   
    Myvector c2;   
    c2.push_back(4);   
    c2.push_back(4);   
    Myvector c3(2, 0);   
  
// display initial contents " 4 3" and " 4 4"   
    for each (int elem in c1)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
    for each (int elem in c2)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
// transform and display   
    cliext::less<int> less_op;   
  
    cliext::transform(c1.begin(), c1.begin() + 2,   
        c2.begin(), c3.begin(),   
        cliext::binary_negate<cliext::less<int> >(less_op));   
    for each (int elem in c3)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
// transform and display with function   
    cliext::transform(c1.begin(), c1.begin() + 2,   
        c2.begin(), c3.begin(), cliext::not2(less_op));   
    for each (int elem in c3)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
    return (0);   
    }
