The TrackDefault() getter method of the TrackDefaultList interface allows the TrackDefault objects in the list to be accessed with an array operator (i.e. [].)
The add() method of the DataStore interface adds a new record to the data store; if the record you are attempting to add already exists, it will throw an exception.
The sync() method of the DataStore interface opens a cursor that allows you to step through any changes that have taken place in the data store going back to a particular revision ID, and run code in response to different types of change.
