bind2nd (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 bind2nd (STL/CLR).
Generates a binder2nd for an argument and functor.
Syntax
template<typename Fun,
typename Arg>
binder2nd<Fun> bind2nd(Fun% functor,
Arg right);
Template Parameters
Arg
The type of the argument.
Fun
The type of the functor.
Function Parameters
functor
The functor to wrap.
right
The second argument to wrap.
Remarks
The template function returns binder2nd (STL/CLR)<Fun>(functor, right). You use it as a convenient way to wrap a two-argument functor and its second argument in a one-argument functor that calls it with a first argument.
Example
// cliext_bind2nd.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 c3(2, 0);
// display initial contents " 4 3"
for each (int elem in c1)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
// transform and display
cliext::minus<int> sub_op;
cliext::binder2nd<cliext::minus<int> > sub4(sub_op, 4);
cliext::transform(c1.begin(), c1.begin() + 2, c3.begin(),
sub4);
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(),
bind2nd(sub_op, 4));
for each (int elem in c3)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
return (0);
}
