Module Theory.System

The Operating System.

include KB.Enum.S with type t = system
type t = system

declare ?package name declares a new element of the enumeration.

Fails if the name is already declared.

val declare : ?package:string -> string -> t

declare ?package name declares a new element of the enumeration.

Fails if the name is already declared.

val read : ?package:string -> string -> t

read ?package name reads the element from its textual representation.

Fails if the name doesn't represent a previously declared element of the enumeration.

If name is unqualified then package is used as the package name. The package itself defaults to "user".

See also of_string s from the Stringable interface which is equal to read s

name x is the name that corresponds to the element x

val unknown : t

unknown is the placeholder for unknown element.

val is_unknown : t -> bool

is_unknown t is true if t is unknown.

domain the type class implementing the domain structure.

Each enumeration type forms a flat domain with the unknown element at the bottom.

persistent the persistance type class.

The enumeration types are persistent and are derived from the KB.Name.persistent type class, i.e., they are represented as 63-bit numbers.

val hash : t -> int

the hash value of the enum

val members : unit -> t list

members () the list of all members of the enumeration type.
