After setting the configuration properties (see Basic example: Using the ApplicationUpdaterUI version), call the initialize() method
to initialize the update:
appUpdater.initialize();
This method does the following:
It initializes the update framework, silently installing
synchronously any pending updates. It is required to call this method
during application startup because it may restart the application
when it is called.
It checks if there is a postponed update and installs it.
If there is an error during the update process, it clears
the update file and version information from the application storage
area.
If the delay has expired, it starts the update process. Otherwise
it restarts the timer.
Calling this method can result in the updater object dispatching
the following events:
Upon dispatching the UpdateEvent.INITIALIZED event,
the update process is completed.
When you call the initialize() method, the updater
starts the update process, and completes all steps, based on the
timer delay setting. However, you can also start the update process
at any time by calling the checkNow() method of
the updater object:
appUpdater.checkNow();
This method does nothing if the update process is already running.
Otherwise, it starts the update process.
The updater object can dispatch the following event as a result
of the calling the checkNow() method:
If you cancel the checkForUpdate event, you
can call the checkForUpdate() method of the updater
object. (See the next section.) If you do not cancel the event,
the update process proceeds to check for the update descriptor file.
