Module PdgIndex.Key

The keys can be used to identify an element of a function. Have a look at the type t to know which kind of elements can be identified.

type key = private
| SigKey of Signature.key(*

key for an element of the function signature

*)
| VarDecl of Frama_c_kernel.Cil_types.varinfo(*

variable declaration

*)
| Stmt of Frama_c_kernel.Cil_types.stmt(*

any statement, except a call

*)
| CallStmt of Frama_c_kernel.Cil_types.stmt(*

call statement

*)
| Label of Frama_c_kernel.Cil_types.stmt * Frama_c_kernel.Cil_types.label(*

program label

*)
| SigCallKey of Frama_c_kernel.Cil_types.stmt * Signature.key(*

key for an element of a call signature

*)

val name : string

Unique name of the datatype.

Datatype descriptor.

Packed version of the descriptor.

val reprs : t list

List of representants of the descriptor.

val equal : t -> t -> bool

Equality: same spec than Stdlib.(=).

val compare : t -> t -> int

Comparison: same spec than Stdlib.compare.

val hash : t -> int

Hash function: same spec than Hashtbl.hash.

val pretty : Stdlib.Format.formatter -> t -> unit

Pretty print each value in an user-friendly way.

val mem_project : ( Frama_c_kernel.Project_skeleton.t -> bool ) -> t -> bool

mem_project f x must return true iff there is a value p of type Project.t in x such that f p returns true.

val copy : t -> t

Deep copy: no possible sharing between x and copy x.
