NAME

  not1  - Function adaptor used to reverse the sense of a unary predicate
  function object.

SYNOPSIS

  #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 provides 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.
