not2 (STL/CLR)

Generates a binary_negate for a functor.

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

Fun

The type of the functor.

functor

The functor to wrap.

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.
