not1 (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 not1 (STL/CLR).
Generates a unary_negate for a functor.
Syntax
template<typename Fun>
unary_negate<Fun> not1(Fun% functor);
Template Parameters
Fun
The type of the functor.
Function Parameters
functor
The functor to wrap.
Remarks
The template function returns unary_negate (STL/CLR)<``Fun``>(functor). You use it as a convenient way to wrap a one-argument functor in a functor that delivers its logical NOT.
Example
// cliext_not1.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(0);
Myvector c3(2, 0);
// display initial contents " 4 0"
for each (int elem in c1)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
// transform and display
cliext::logical_not<int> not_op;
cliext::transform(c1.begin(), c1.begin() + 2, c3.begin(),
cliext::unary_negate<cliext::logical_not<int> >(not_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, c3.begin(),
cliext::not1(not_op));
for each (int elem in c3)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
return (0);
}
