NAME
not2 - Function adaptor used to reverse the sense of a binary predicate
function object.
SYNOPSIS
#include <functional>
template <class Predicate>
binary_negate<Predicate> not2 (const Predicate& pred);
DESCRIPTION
not2 is a function adaptor, known as a negator, that takes a binary
predicate function object as its argument and returns a binary predicate
function object that is the complement of the original. binary_negate is a
function object class that provides a return type for the not2 negator.
Note that not2 works only with function objects that are defined as
subclasses of the class binary_function.
