module MakeArray (X : ORDERED) : S with type key = X.t array and type char_ = X.t
type
type
type 'a t
val empty : 'a t
val is_empty : 'a t -> bool
val add : key -> 'a -> 'a t -> 'a t
Add a binding to the trie (possibly erasing the previous one)
val remove : key -> 'a t -> 'a t
Remove the key, if present
val find : key -> 'a t -> 'a option
Find the value associated with the key, if any
val find_exn : key -> 'a t -> 'a
Same as
CCTrie.S.find but can fail.
Raises Not_found if the key is not present
val longest_prefix : key -> 'a t -> key
longest_prefix k m finds the longest prefix of
k that leads to
at least one path in
m (it does not mean that the prefix is bound to
a value.
Example: if m has keys "abc0" and "abcd", then longest_prefix "abc2" m
will return "abc"
Since 0.17
val update : key -> ('a option -> 'a option) -> 'a t -> 'a t
Update the binding for the given key. The function is given
None if the key is absent, or Some v if key is bound to v;
if it returns None the key is removed, otherwise it
returns Some y and key becomes bound to y
val fold : ('b -> key -> 'a -> 'b) -> 'b -> 'a t -> 'b
val mapi : (key -> 'a -> 'b) -> 'a t -> 'b t
Map values, giving both key and value. Will use
CCTrie.WORD.of_list to rebuild keys.
Since 0.17
val map : ('a -> 'b) -> 'a t -> 'b t
Map values, giving only the value.
Since 0.17
val iter : (key -> 'a -> unit) -> 'a t -> unit
val fold_values : ('b -> 'a -> 'b) -> 'b -> 'a t -> 'b
val iter_values : ('a -> unit) -> 'a t -> unit
val merge : ('a -> 'a -> 'a option) -> 'a t -> 'a t -> 'a t
Merge two tries together. The function is used in
case of conflicts, when a key belongs to both tries
val size : 'a t -> int
Number of bindings

Ranges
val above : key -> 'a t -> (key * 'a) CCTrie.sequence
All bindings whose key is bigger or equal to the given key, in
ascending order
val below : key -> 'a t -> (key * 'a) CCTrie.sequence
All bindings whose key is smaller or equal to the given key,
in decreasing order
