camomile 0.8.7 · OCaml Package

Sets of Unicode characters, implemented as sets of intervals. The signature is mostly same to Set.S in stdlib

type t

val empty : t

val is_empty : t -> bool

val mem : UChar.t -> t -> bool

val add : UChar.t -> t -> t

val add_range : UChar.t -> UChar.t -> t -> t

add_range u1 u2 s adds the characters in the range u1 - u2 to s. The range is determined by the code point order.

val singleton : UChar.t -> t

val remove : UChar.t -> t -> t

val remove_range : UChar.t -> UChar.t -> t -> t

remove_range u1 u2 s removes the characters in the range u1 - u2 from s. The range is determined by the code point order.

val union : t -> t -> t

val inter : t -> t -> t

val diff : t -> t -> t

val compl : t -> t

compl s returns the compliment of s.

val compare : t -> t -> int

val equal : t -> t -> bool

val subset : t -> t -> bool

val from : UChar.t -> t -> t

from u s returns the set of elements of s whose code points are equal or greater than u.

val after : UChar.t -> t -> t

after u s returns the set of elements of s whose code points are greater than u.

val until : UChar.t -> t -> t

until u s returns the set of elements of s whose code points are equal or smaller than u.

val before : UChar.t -> t -> t

until u s returns the set of elements of s whose code points are smaller than u.

val iter : (UChar.t -> unit) -> t -> unit

val iter_range : (UChar.t -> UChar.t -> unit) -> t -> unit

iter_range proc s feeds the intervals contained in s to proc in increasing order. The intervals given to proc are always separated by the character not in s.

val fold : (UChar.t -> 'a -> 'a) -> t -> 'a -> 'a

val fold_range : (UChar.t -> UChar.t -> 'a -> 'a) -> t -> 'a -> 'a

fold_range f s x is equivalent to f u_i u_(i+1) (... (f u_3 u_4 (f u_1 u_2 x))) if s is consisted of the intervals u1-u2, u3-u4, ..., u_i-u_(i + 1) in increasing order. The intervals given to proc are always separated by the character not in s.

val for_all : (UChar.t -> bool) -> t -> bool

val exists : (UChar.t -> bool) -> t -> bool

val filter : (UChar.t -> bool) -> t -> t

val partition : (UChar.t -> bool) -> t -> t * t

val cardinal : t -> int

val elements : t -> UChar.t list

val ranges : t -> (UChar.t * UChar.t) list

The list of the intervals contained in the set. The returned intervals are always separated by the character not in s.

val min_elt : t -> UChar.t

val max_elt : t -> UChar.t

val choose : t -> UChar.t

Returns a element roughly in the middle of the set. It is not guaranteed to return the same element for the sets with the same elements

val uset_of_iset : ISet.t -> t

val iset_of_uset : t -> ISet.t
