/**
|
|
* nsIObserver topics for profile changing. Profile changing happens in phases
|
|
* in the order given below. An observer may register separately for each phase
|
|
* of the process depending on its needs. The subject passed to the observer's
|
|
* Observe() method can be QI'd to an nsIProfileChangeStatus.
|
|
*
|
|
* "profile-approve-change"
|
|
* Called before a profile change is attempted. Typically,
|
|
* the application level observer will ask the user if
|
|
* he/she wants to stop all network activity, close all open
|
|
* windows, etc. If the user says NO, the observer should
|
|
* call the subject's vetoChange(). If any observer does
|
|
* this, the profile will not be changed.
|
|
*
|
|
* "profile-change-teardown"
|
|
* All async activity must be stopped in this phase. Typically,
|
|
* the application level observer will close all open windows.
|
|
* This is the last phase in which the subject's vetoChange()
|
|
* method may still be called.
|
|
* The next notification will be either
|
|
* profile-change-teardown-veto or profile-before-change.
|
|
*
|
|
* "profile-change-teardown-veto"
|
|
* This notification will only be sent, if the profile change
|
|
* was vetoed during the profile-change-teardown phase.
|
|
* This allows components to bring back required resources,
|
|
* that were tore down on profile-change-teardown.
|
|
*
|
|
* "profile-before-change"
|
|
* Called before the profile has changed. Use this notification
|
|
* to prepare for the profile going away. If a component is
|
|
* holding any state which needs to be flushed to a profile-relative
|
|
* location, it should be done here.
|
|
*
|
|
* "profile-do-change"
|
|
* Called after the profile has changed. Do the work to
|
|
* respond to having a new profile. Any change which
|
|
* affects others must be done in this phase.
|
|
*
|
|
* "profile-after-change"
|
|
* Called after the profile has changed. Use this notification
|
|
* to make changes that are dependent on what some other listener
|
|
* did during its profile-do-change. For example, to respond to
|
|
* new preferences.
|
|
*
|
|
* "profile-initial-state"
|
|
* Called after all phases of a change have completed. Typically
|
|
* in this phase, an application level observer will open a new window.
|
|
*
|
|
* Contexts for profile changes. These are passed as the someData param to the
|
|
* observer's Observe() method.
|
|
|
|
* "startup"
|
|
* Going from no profile to a profile.
|
|
*
|
|
* The following topics happen in this context:
|
|
* profile-do-change
|
|
* profile-after-change
|
|
*
|
|
* "shutdown-persist"
|
|
* The user is logging out and whatever data the observer stores
|
|
* for the current profile should be released from memory and
|
|
* saved to disk.
|
|
*
|
|
* "shutdown-cleanse"
|
|
* The user is logging out and whatever data the observer stores
|
|
* for the current profile should be released from memory and
|
|
* deleted from disk.
|
|
*
|
|
* The following topics happen in both shutdown contexts:
|
|
* profile-approve-change
|
|
* profile-change-teardown
|
|
* profile-before-change
|
|
*
|
|
* "switch"
|
|
* Going from one profile to another.
|
|
*
|
|
* All of the above topics happen in a profile switch.
