A functor, or function object, is a class in C++ with the () operator overloaded. Functors are used a lot in the standard library to do custom comparisons. They're used in place of function pointers because sometimes you need to store a value or remember something (ie. put the functor into a special 'state' for whatever purpose), a functor can do this, a function pointer can't (without messing with global variables).
class over5 { // this class is the functor
bool operator() (int x) {
return x > 5;
}
};
std::list<int> L;
... // put a bunch of ints onto the list
over5 o5;
std::find_if(L.begin(), L.end(), o5);
// o5 will have its overloaded () operator called to check if the element in L is over 5.
bool operator() (int x) {
return x > 5;
}
};
std::list<int> L;
... // put a bunch of ints onto the list
over5 o5;
std::find_if(L.begin(), L.end(), o5);
// o5 will have its overloaded () operator called to check if the element in L is over 5.

Get the functor mug.Corollary of gesture-theory (theory-of-action) in which humans are functors and symbols are actors.
Gesture-theory implies that action is the control of space. Thus symbols human beings make--such as gestures--not human beings themselves; control space.
Color is the only actor (space-controller) that is not a symbol and also acts as a functor.

Color-as-functor implies that color precedes consciousness FROM THE FUTURE indicating that colors may be conscious (chakras).

Often a useless piece of information, but can be used as an ice breaker to start conversation.
"Shrimps can only swim backward" or "A ball of glass will bounce higher than a ball of rubber" are both functoids.

Get the Funstorm mug.Originally coined by software developers, fuctoring has broad business applicability. Fuctoring is the process of adding unnecessary complexity or byzantine logic and process to fight your inevitable career obsolescence. Fuctoring ensures the bulk of your work output is not usable by others in your absence.
"I know I could do this simply, but a little well-planned fuctoring will make it much harder for them to fire me."
