#include <functional>
template<class Predicate>
unary_negate <Predicate> not1 (const Predicate&);
 
 
 

DESCRIPTION

 
 
not1 is a function adaptor, known as a negator, that takes a unary predicate function object as its argument and returns a unary predicate function object that is the complement of the original. unary_negate is a function object class that includes a return type for the not1_negator.
 
Note that not1 works only with function objects that are defined as subclasses of the class unary_function.
