NAME

 
not2
 
 - A 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 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.
