Frama-C API - Typed_parameter

Parameter settable through a command line option. This is a low level API, internally used by the kernel. As a plug-in developer, you certainly prefer to use the API of Plugin instead.

generic accessor type

type 'a accessor = ('a, 'a) gen_accessor
type typed_accessor =
  1. | Bool of bool accessor * string option
    (*

    the negative option, if any

    *)
  2. | Int of int accessor * unit -> int * int
    (*

    getting range

    *)
  3. | Float of float accessor * unit -> float * float
    (*

    getting range

    *)
  4. | String of string accessor * unit -> string list
    (*

    possible values

    *)
type parameter = private {
  1. name : string;
    (*

    Name of the option corresponding to the parameter. It is exactly the state name of the option (see State.get_name).

    *)
  2. help : string;
    (*

    Help message

    *)
  3. accessor : typed_accessor;
    (*

    How to get and set the value of the parameter

    *)
  4. visible : bool;
    (*

    Is visible to the user, e.g. in the command-line help

    *)
  5. safe : bool;
    (*

    Can be used in sandbox mode

    *)
  6. reconfigurable : bool;
    (*

    Can be reconfigured, e.g. in the GUI

    *)
  7. is_set : unit -> bool;
    (*

    Is this option really set?

Datatype descriptor.

val packed_descr : Structural_descr.pack

Packed version of the descriptor.

val reprs : t list

List of representants of the descriptor.
