/**
|
|
* Sync's XPCOM service.
|
|
*
|
|
* It is named "Weave" for historical reasons.
|
|
*
|
|
* It's worth noting how Sync is lazily loaded. We register a timer that
|
|
* loads Sync a few seconds after app startup. This is so Sync does not
|
|
* adversely affect application start time.
|
|
*
|
|
* If Sync is not configured, no extra Sync code is loaded. If an
|
|
* external component (say the UI) needs to interact with Sync, it
|
|
* should do something like the following:
|
|
*
|
|
* // 1. Grab a handle to the Sync XPCOM service.
|
|
* let service = Cc["@mozilla.org/weave/service;1"]
|
|
* .getService(Components.interfaces.nsISupports)
|
|
* .wrappedJSObject;
|
|
*
|
|
* // 2. Check if the service has been initialized.
|
|
* if (service.ready) {
|
|
* // You are free to interact with "Weave." objects.
|
|
* return;
|
|
* }
|
|
*
|
|
* // 3. Install "ready" listener.
|
|
* Services.obs.addObserver(function onReady() {
|
|
* Services.obs.removeObserver(onReady, "weave:service:ready");
|
|
*
|
|
* // You are free to interact with "Weave." objects.
|
|
* }, "weave:service:ready", false);
|
|
*
|
|
* // 4. Trigger loading of Sync.
|
|
* service.ensureLoaded();
