bind1st (STL/CLR)
The latest version of this topic can be found at bind1st (STL/CLR).
Generates a binder1st for an argument and functor.
Syntax
template<typename Fun,
typename Arg>
binder1st<Fun> bind1st(Fun% functor,
Arg left);
Template Parameters
Arg
The type of the argument.
Fun
The type of the functor.
Function Parameters
functor
The functor to wrap.
left
The first argument to wrap.
Remarks
The template function returns binder1st (STL/CLR)<Fun>(functor, left). You use it as a convenient way to wrap a two-argument functor and its first argument in a one-argument functor that calls it with a second argument.
Example
// cliext_bind1st.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::binder1st<cliext::minus<int> > subfrom3(sub_op, 3);
cliext::transform(c1.begin(), c1.begin() + 2, c3.begin(),
subfrom3);
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(),
bind1st(sub_op, 3));
for each (int elem in c3)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
return (0);
}
