Class type

Hashtable indexed by kernel functions and dealing with project.

Parameters

module Data : Datatype.S
module _ : State_builder.Info_with_size

Signature

Hashtbl are a standard computation. BUT that is INCORRECT to use projectified hashtables if keys have a custom rehash function (see Datatype.Make_input.rehash)

include State_builder.S
val self : State.t

The kind of the registered state.

val name : string
val mark_as_computed : ?project:Project.t -> unit -> unit

Indicate that the registered state will not change again for the given project (default is current ()).

val is_computed : ?project:Project.t -> unit -> bool

Returns true iff the registered state will not change again for the given project (default is current ()).

Exportation of some inputs (easier use of State_builder.Register).

val add_hook_on_update : (Datatype.t -> unit) -> unit

Add an hook which is applied each time (just before) the project library changes the local value of the state.

val howto_marshal : (Datatype.t -> 'a) -> ('a -> Datatype.t) -> unit

howto_marshal marshal unmarshal registers a custom couple of functions (marshal, unmarshal) to be used for serialization. Default functions are identities. In particular, this function must be used if Datatype.t is not marshallable and do_not_save is not called.

type key = t
type data = Data.t
val replace : key -> data -> unit

Add a new binding. The previous one is removed.

val add : key -> data -> unit

Add a new binding. The previous one is only hidden.

val clear : unit -> unit

Clear the table.

val length : unit -> int

Length of the table.

val iter : (key -> data -> unit) -> unit
val iter_sorted : ?cmp:(key -> key -> int) -> (key -> data -> unit) -> unit
val fold : (key -> data -> 'a -> 'a) -> 'a -> 'a
val fold_sorted : ?cmp:(key -> key -> int) -> (key -> data -> 'a -> 'a) -> 'a -> 'a
val memo : ?change:(data -> data) -> (key -> data) -> key -> data

Memoization. Compute on need the data associated to a given key using the given function. If the data is already computed, it is possible to change with change.

val find : key -> data

Return the current binding of the given key.

  • raises Not_found

    if the key is not in the table.

val find_opt : key -> data option

Return the current binding of the given key, or None if no such binding exists.

  • since 27.0-Cobalt
val find_all : key -> data list

Return the list of all data associated with the given key.

val mem : key -> bool
val remove : key -> unit
val to_seq : unit -> (key * data) Stdlib.Seq.t

Iterate on the whole table.

  • since 27.0-Cobalt
val add_hook_on_change : ((key, data) State_builder.hashtbl_event -> unit) -> unit

Add an hook which is applied each time (just after) a (key,value) pair in the hashtable changes inside the current project.

  • since 28.0-Nickel
