Module CCOrd

module CCOrd: sig .. end


type 'a t = 'a -> 'a -> int 
Comparison (total ordering) between two elements, that returns an int
val compare : 'a t
Polymorphic "magic" comparison
val opp : 'a t -> 'a t
Opposite order
val equiv : int -> int -> bool
Returns true iff the two comparison results are the same
val int : int t
val string : string t
val bool : bool t
val float : float t

Lexicographic Combination

val (<?>) : int -> 'a t * 'a * 'a -> int
c1 <?> (ord, x, y) returns the same as c1 if c1 is not 0; otherwise it uses ord to compare the two values x and y, of type 'a.

Example: 1 3
      <?> (, "a", "b")
      <?> (, true, false)

Same example, using only CCOrd::

CCOrd.(int 1 3
        <?> (string, "a", "b")
        <?> (bool, true, false))

val option : 'a t -> 'a option t
Comparison of optional values. None is smaller than any Some _.
Since 0.15
val pair : 'a t -> 'b t -> ('a * 'b) t
val triple : 'a t -> 'b t -> 'c t -> ('a * 'b * 'c) t
val list : 'a t -> 'a list t
Lexicographic combination on lists
val array : 'a t -> 'a array t
val map : ('a -> 'b) -> 'b t -> 'a t
map f ord is the comparison function that, given objects x and y, projects x and y using f (e.g. using a record field) and then compares those projections with ord. Example: map fst compares values of type (int * 'a) by their first component.
val (>|=) : 'b t -> ('a -> 'b) -> 'a t
