Std.Tid
Term identifier.
A term identifier is a knowledge object of class core-theory:program
that represents a program. Objects of this class have many properties that describe program syntax (representation) and semantics. The set of properties is extensible and each plugin/library can add its own properties, for the current set of all properties of all classes, see bap list classes
, or bap list class -f core-theory:program
to list the properties of the class to which Tid.t belongs.
type t = tid
val create : unit -> t
create ()
creates a fresh newly term identifier.
This function has a side-effect of changing the Toplevel knowledge base.
val for_name : ?package:string -> string -> t
for_name name
creates a Term identifier for the given name
.
Creates a new program object that denotes a program with the given name. See Theory.Label.for_name
from the Bap_core_theory
interface for more information.
for_addr addr
creates a Term identifier for the given addr
.
Creates a new program object that denotes a program with the given addr. See Theory.Label.for_addr
from the Bap_core_theory
interface for more information.
val for_ivec : ?package:string -> int -> t
for_ivec ivec
creates a Term identifier for the given ivec
.
Creates a new program object that denotes a program with the given ivec. See Theory.Label.for_ivec
from the Bap_core_theory
interface for more information.
val set_name : tid -> string -> unit
set_name tid name
associates a name
with a given term identifier tid
. Any previous associations are overridden.
val name : tid -> string
name tid
returns a term name: either a string name with at-prefix, or number identifier.
val from_string : string -> tid Core_kernel.Or_error.t
from_string s
parses tid from string. The expected format is:
tid = symbol | number. symbol = "@", string. number = "%", hex. string = ?sequence of characters?. number = ?ocaml hexadecimal representation?.
val from_string_exn : string -> tid
from_string_exn s
same as from_string_exn
but throws exception on error.
val (!!) : string -> tid
infix notation for from_string_exn

is formatted output function that matches "%a" conversion format specifier in functions, that prints to string, e.g., sprintf
, failwithf
, errorf
and, surprisingly all Lwt
printing function, including Lwt_io.printf
and logging (or any other function with type ('a,unit,string,...) formatN`. Example:
Or_error.errorf "type %a is not valid for %a"
Type.str ty Exp.str exp
val pps : unit -> t -> string
synonym for str
val ppo : Core_kernel.Out_channel.t -> t -> unit

information attached to a particular reader or writer.
Data representation version. After any change in data representation the version should be increased.
Serializers that are derived from a data representation must have the same version as a version of the data structure, from which it is derived. This kind of serializers can only read and write data of the same version.
Other serializers can actually read and write data independent on its representation version. A serializer, that can't store data of current version simply shouldn't be added to a set of serializers.
It is assumed, that if a reader and a writer has the same name and version, then whatever was written by the writer should be readable by the reader. The round-trip equality is not required, thus it is acceptable if some information is lost.
It is also possible, that a reader and a writer that has the same name are compatible. In that case it is recommended to use semantic versioning.
val size_in_bytes : ?ver:string -> ?fmt:string -> t -> int
