Functor SetList.Make

module Make: 
functor (Ord : Set.OrderedType) -> S with type elt = Ord.t
Functor building an implementation of the SetList structure given a totally ordered type.
Parameters:
Ord : Set.OrderedType

type elt 
The type of the set elements.
type t 
The type of sets.
val print : ?first:(unit, Format.formatter, unit) Pervasives.format ->
?sep:(unit, Format.formatter, unit) Pervasives.format ->
?last:(unit, Format.formatter, unit) Pervasives.format ->
(Format.formatter -> elt -> unit) ->
Format.formatter -> t -> unit
Printing function
val empty : t
The empty set.
val is_empty : t -> bool
Test whether a set is empty or not.
val mem : elt -> t -> bool
mem x s tests whether x belongs to the set s.
val of_list : elt list -> t
Conversion from a list (unsafe operation)
val to_list : t -> elt list
Conversion to a list
val singleton : elt -> t
singleton x returns the one-element set containing only x.
val add : elt -> t -> t
add x s returns a set containing all elements of s, plus x. If x was already in s, s is returned unchanged.
val remove : elt -> t -> t
remove x s returns a set containing all elements of s, except x. If x was not in s, s is returned unchanged.
val union : t -> t -> t
val inter : t -> t -> t
val diff : t -> t -> t
Union, intersection and set difference.
val compare : t -> t -> int
Total ordering between sets. Can be used as the ordering function for doing sets of sets.
val equal : t -> t -> bool
equal s1 s2 tests whether the sets s1 and s2 are equal, that is, contain equal elements.
val subset : t -> t -> bool
subset s1 s2 tests whether the set s1 is a subset of the set s2.
val iter : (elt -> unit) -> t -> unit
iter f s applies f in turn to all elements of s. The order in which the elements of s are presented to f is in ascending order.
val fold : (elt -> 'a -> 'a) -> t -> 'a -> 'a
fold f s a computes (f xN ... (f x2 (f x1 a))...), where x1 ... xN are the elements of s. The order in which elements of s are presented to f is in ascending order.
Raises Not_found if no fount
Returns the computed accumulator
val fold_right : (elt -> 'a -> 'a) -> t -> 'a -> 'a
val fold_left : ('a -> elt -> 'a) -> 'a -> t -> 'a
Idem as List.fold_X functions
val cardinal : t -> int
Return the number of elements of a set.
val elements : t -> elt list
Return the list of all elements of the given set. The returned list is sorted in increasing order.
val min_elt : t -> elt
Return the smallest element of the given set (with respect to the Ord.compare ordering), or raise Not_found if the set is empty.
val max_elt : t -> elt
Same as min_elt, but returns the largest element of the given set.
val choose : t -> elt
Return one element of the given set, or raise Not_found if the set is empty. Which element is chosen is unspecified, but equal elements will be chosen for equal sets.
val filter : (elt -> bool) -> t -> t
filter p s returns the set of all elements in s that satisfy predicate p.
val partition : (elt -> bool) -> t -> t * t
partition p s returns a pair of sets (s1, s2), where s1 is the set of all the elements of s that satisfy the predicate p, and s2 is the set of all the elements of s that do not satisfy p.
val exists : (elt -> bool) -> t -> bool
exists p s checks if at least one element of the set satisfies the predicate p.
val for_all : (elt -> bool) -> t -> bool
for_all p s checks if all elements of the set satisfy the predicate p.
