- A function adaptor used to reverse the sense of a binary
predicate function object.
template <class Predicate>
binary_negate<Predicate> not2 (const Predicate& pred);
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
includes 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.
