public interface WGDatabaseConnectListener
A listener that will get notified, when the database is connected to its backend.
This event only occurs, when the database was not opened normally but only prepared for
opening by using WGFactory.prepareDatabase. In this mode the database will only test its
connectivity to the backend but disconnect from it directly after that.
The connection is reestablished with the first session that is opened. At this time
the event is fired. The database has an open session when this event is fired.
It is guaranteed, that the listeners will be called in the order that they were registered
with the database.
