Description
binary_negate is a function object class that provides a return type for the function adaptor not2. 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.
Note that not2 works only with function objects that are defined as subclasses of the class
binary_function.
