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 ()).

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 data = Data.t

Type of the referenced value.

val set : data -> unit

Change the referenced value.

val get : unit -> data

Get the referenced value.

val clear : unit -> unit

Reset the reference to its default value.

val memo : ?change:(data -> data) -> (unit -> data) -> data

Memoization. Compute on need the stored value. If the data is already computed (i.e. is not None), it is possible to change with change.
