type 'a t

trie can store arbitrary data

type key = Corpus.key

a key type that is used to lookup data

val create : unit -> 'a t

create () creates new empty trie

val add : 'a t -> key:key -> data:'a -> unit

add trie ~key ~data associates data with key. If trie already has some value associated with key, then the value will be overwritten (rebound)

val change : 'a t -> key -> ('a option -> 'a option) -> unit

change trie key f if trie has data associated with key then f will be called with Some data, otherwise it will be called with None. If f returns None then there will be no data associated with key, if f returns Some thing, then thing will be associated with key

val find : 'a t -> key -> 'a option

find trie key finds data associated with key

val walk : 'a t -> key -> init:'b -> f:('b -> 'a option -> 'b) -> 'b

walk trie key ~init ~f walks down the tree starting from the root and ending with the last token of the key. Function f is fold over values associated with all substrings of the key, starting from a zero substring.

val remove : 'a t -> key -> unit

remove trie key removes value bound with key if any.

val longest_match : 'a t -> key -> (int * 'a) option

longest_match trie key find a value associated with a longest substring of key. Returns a pair - a length of matched key and the value, associated with that key.

val length : 'a t -> int

length trie returns the number of values in trie

val pp : 
  (Stdlib.Format.formatter -> 'a -> unit) ->
  Stdlib.Format.formatter ->
  'a t ->
  unit

pp pp_val creates a printer for a given value printer pp_val. Example:

let int_trie = String.Trie.pp pp_int

will create a printer for a String.Trie that is populated by integers.

type token

val fold : 'a t -> init:'b -> f:('b -> token list -> 'a -> 'b) -> 'b

fold trie init f folds over all elements of trie.

The function f x key data is applied to all elements of trie which were previously added. The key is represented as a list of tokens.

val iter : 'a t -> f:(token list -> 'a -> unit) -> unit

iter trie f iterates over all element of trie.

The function f key data is applied to all elements of trie which were previously added. The key is represented as a list of tokens.

val make_printer : 
  (Stdlib.Format.formatter -> token list -> unit) ->
  (Stdlib.Format.formatter -> 'a -> unit) ->
  Stdlib.Format.formatter ->
  'a t ->
  unit

make_printer print_tokens print_data create a trie printer.

Creates a function that will print a trie using print_token to print the key in the form of a token list, and print_data to print data associated with keys.

Only those keys that have associated data are printed (i.e., those that were added to the trie).

Each key value pair is printed as using the following format specification: "@[<2>%a@ %a@]@;". So it is advised to print it in a vertical box.
