Interface CompactOnLaunchCallback

All Known Implementing Classes:

DefaultCompactOnLaunchCallback

public interface CompactOnLaunchCallback

This interface is used to determine if a Realm file should be compacted the first time the file is opened and before the instance is returned.

Note that compacting a file can take a while, so compacting should generally only be done on a background thread or when used in combination with Realm.getInstanceAsync(RealmConfiguration, io.realm.Realm.Callback).
