module Make: functor (Ord : Set.OrderedType) -> S with type elt = Ord.t
and module Ord=Ord
Functor building an implementation of the set structure
given a totally ordered type.
type
The type of the set elements.
type
The type of sets.
module Ord: Set.OrderedType with type t=elt
The ordering module used for this set module.
val repr : t -> elt Sette.tzz
val obj : elt Sette.tzz -> t
val splitzz : elt ->
elt Sette.tzz -> elt Sette.tzz * bool * elt Sette.tzz
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 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 singleton : elt -> t
singleton x returns the one-element set containing only x.
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
Set union.
val inter : t -> t -> t
Set intersection.
val diff : t -> t -> t
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 unspecified.
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
unspecified.
val for_all : (elt -> bool) -> t -> bool
for_all p s checks if all elements of the set
satisfy the predicate p.
val exists : (elt -> bool) -> t -> bool
exists p s checks if at least one element of
the set satisfies the predicate p.
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 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 with respect
to the ordering
Ord.compare, where
Ord is the argument
given to
Sette.Make.
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
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 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
