Class type Wd_types.session_type

class type session_type = object .. end

This is a single session

method session_id : string

Returns the ID of the session. Fails if the session does not have an ID (e.g. it is not stored in the database)

method dialog_name : string

Returns the name of the dialog this session encapsulates

method dialog : dialog_type

Returns the dialog

method commit_changes : unit -> unit

Causes that serialize returns the current state of the dialog. This means that commit_changes extracts the state from the dialog, and prepares the string that will be returned by serialize.

method serialize : string

Returns the state of the dialog at the time of the last commit_change or the state of the initial dialog

method change_dialog : dialog_type -> unit

Continue with a new dialog. The methods dialog_name and dialog will immediately reflect the change. However, you have to call commit_changes to make serialize return the state of the new dialog.
