not2 (STL/CLR)
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);
