Module Eliom_reference.Volatile.Ext

module Ext : sig..end

This module allows access to volatile references for other groups, sessions, or client processes. Use it in conjunction with functions like Eliom_state.Ext.iter_volatile_sub_states to get the sessions from a group (or the processes from a session).

val get : 
  ([< `Client_process | `Session | `Session_group ], [< `Data ])
  Eliom_state.Ext.state -> 'a Eliom_reference.Volatile.eref -> 'a

get the value of a reference from outside the state. If the value has not been set yet for this state, it will raise exception Eref_not_initialized.

val set : 
  ([< `Client_process | `Session | `Session_group ], [< `Data ])
  Eliom_state.Ext.state ->
  'a Eliom_reference.Volatile.eref -> 'a -> unit

val modify : 
  ([< `Client_process | `Session | `Session_group ], [< `Data ])
  Eliom_state.Ext.state ->
  'a Eliom_reference.Volatile.eref -> ('a -> 'a) -> unit

Warning: the function will be executed with the current context

val unset : 
  ([< `Client_process | `Session | `Session_group ], [< `Data ])
  Eliom_state.Ext.state -> 'a Eliom_reference.Volatile.eref -> unit
