.SH  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.
