module RefList: BatRefList
exception Empty_list
type 'a
t
The type of an empty ref list
val empty : unit -> 'a t
Returns a new empty ref list
val is_empty : 'a t -> bool
Return true
if a ref list is empty
val clear : 'a t -> unit
Removes all elements
val length : 'a t -> int
Returns the number of elements - O(n)
val copy : dst:'a t -> src:'a t -> unit
Makes a copy of a ref list - O(1)
val copy_list : dst:'a t -> src:'a list -> unit
Makes a copy of a list - O(1)
val copy_enum : dst:'a t -> src:'a BatEnum.t -> unit

dst
: A reflist, whose contents will be forgotten.val of_list : 'a list -> 'a t
Creates a ref list from a list - O(1)
val to_list : 'a t -> 'a list
Returns the current elements as a list - O(1)
val of_enum : 'a BatEnum.t -> 'a t
Creates a ref list from an enumeration
val enum : 'a t -> 'a BatEnum.t
Returns an enumeration of current elements in the ref list
val of_backwards : 'a BatEnum.t -> 'a t
Creates a ref list from an enumeration, going from last to first
val backwards : 'a t -> 'a BatEnum.t
Returns an enumeration of current elements in the ref list, going from last to first
val add : 'a t -> 'a -> unit
Adds an element at the end - O(n)
val push : 'a t -> 'a -> unit
Adds an element at the head - O(1)
val add_sort : cmp:('a -> 'a -> int) -> 'a t -> 'a -> unit
Adds an element in a sorted list, using the given comparator.
val first : 'a t -> 'a
Returns the first element or
raises Empty_list
if the ref list is empty
val last : 'a t -> 'a
Returns the last element - O(n) or
raises Empty_list
if the ref list is empty
val pop : 'a t -> 'a
Removes and returns the first element or
raises Empty_list
if the ref list is empty
val npop : 'a t -> int -> 'a list
Removes and returns the n first elements or
raises Empty_list
if the ref list does not
contain enough elements
val hd : 'a t -> 'a
same as first
val tl : 'a t -> 'a t
Returns a ref list containing the same elements
but without the first one or
raises Empty_list
if the ref list is empty
val rev : 'a t -> unit
Reverses the ref list - O(n)
val fold_left : ('a -> 'b -> 'a) -> 'a -> 'b t -> 'a
List.fold_left f a (ref [b0; b1; ...; bn])
is
f (... (f (f a b0) b1) ...) bn
.
val fold_right : ('a -> 'b -> 'b) -> 'a t -> 'b -> 'b
List.fold_right f (ref [a0; a1; ...; an]) b
is
f a0 (f a1 (... (f an b) ...))
. Tail-recursive.
val iter : ('a -> unit) -> 'a t -> unit
Apply the given function to all elements of the ref list, in respect with the order of the list
val find : ('a -> bool) -> 'a t -> 'a
Find the first element matching
the specified predicate
raise Not_found
if no element is found
val rfind : ('a -> bool) -> 'a t -> 'a
Find the first element in the reversed ref list matching
the specified predicate
raise Not_found
if no element is found
val find_exn : ('a -> bool) -> exn -> 'a t -> 'a
Same as find but takes an exception to be raised when no element is found as additional parameter.
val find_exc : ('a -> bool) -> exn -> 'a t -> 'a
BatRefList.find_exn
Alias for find_exn
.
val exists : ('a -> bool) -> 'a t -> bool
Return true
if an element matches the specified
predicate
val for_all : ('a -> bool) -> 'a t -> bool
Return true
if all elements match the specified
predicate
val map : ('a -> 'b) -> 'a t -> 'b t
Apply a function to all elements and return the ref list constructed with the function returned values
val transform : ('a -> 'a) -> 'a t -> unit
transform all elements in the ref list using a function.
val map_list : ('a -> 'b) -> 'a t -> 'b list
Apply a function to all elements and return the list constructed with the function returned values
val sort : cmp:('a -> 'a -> int) -> 'a t -> unit
Sort elements using the specified comparator
val filter : ('a -> bool) -> 'a t -> unit
Remove all elements that do not match the specified predicate
val remove : 'a t -> 'a -> unit
Remove an element from the ref list
raise Not_found
if the element is not found
val remove_if : ('a -> bool) -> 'a t -> unit
Remove the first element matching the
specified predicate
raise Not_found
if no element has been removed
val remove_all : 'a t -> 'a -> unit
Remove all elements equal to the specified element from the ref list
module Index:sig
..end
Functions that operate on the element at index i
in a list (with
indices starting from 0).
