Global variables
This module provides a place to store global variables that work
across subprocess boundaries. In order to push values to related processes
it needs a propagator. The propagator is not included here. The
Netplex library implements a propagator that is automatically activated.
Variables are limited to string type.
type
val access : string -> variableaccess name: Create or look up a variable with this name
val get : variable -> stringGet the value of the variable (after checking for an update)
val set : variable -> string -> unitSet the value of the variable
val get_v : variable -> string * int64Get the value and the version number of the variable
val set_v : variable -> string -> int64Set the value and get the new version number
val iter : (string -> string -> int64 -> unit) -> unititer f: for every variable call f name value version
class type propagator =object..end
val get_propagator : unit -> propagator optionGet the current propagator or return None
val set_propagator : propagator option -> unitSet the current propagator to Some p, or remove the propagator with
None
