.SH NAME

\f2not2\fP

\ - A function adaptor used to reverse the sense of a binary predicate function object.



.SH  SYNOPSIS


.br
#include <functional>
.br
template <class Predicate>
.br
binary_negate<Predicate> not2 (const Predicate& pred);



.SH  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 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.
