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 descr : t Frama_c_kernel.Descr.t
Datatype descriptor.
val packed_descr : Frama_c_kernel.Structural_descr.pack
Packed version of the descriptor.
val reprs : t list
List of representants of the descriptor.
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
.
