Frama-C API - Hashconsing_tbl_not_weak
Hash table for hashconsing, but the internal table is _not_ weak (it is a regular hash table). This module should be used only in case perfect reproducibility matters, as the table will never be emptied by the GC.
Parameters
module Data : sig ... end
module _ : Info_with_size
Signature
Hashtbl are a standard computation. BUT it is INCORRECT to use projectified hashtables if keys have a custom rehash
function (see Datatype.Make_input.rehash
)
include S
val self : State.t
The kind of the registered state.
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
).
module Datatype : Datatype.S
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 data = Data.t
merge x
returns an instance of x
found in the table if any, or else adds x
and return x
.
val add : data -> unit
add x
adds x
to the table. If there is already an instance of x
, it is unspecified which one will be returned by subsequent calls to find
and merge
.
val iter : (data -> unit) -> unit
val fold : (data -> 'a -> 'a) -> 'a -> 'a
val mem : data -> bool
mem x
returns true
if there is at least one instance of x
in the table, false
otherwise.
val remove : data -> unit
remove x
removes from the table one instance of x
. Does nothing if there is no instance of x
.
