All Implemented Interfaces:

XLifeCycleListener

public class DatabaseLifecycleListener
extends java.lang.Object
implements XLifeCycleListener

A shutdown/lifecycle listener designed for database like the standalone or in-memory version of HSQLDB. The listener calls SHUTDOWN on the database so as to give the database a chance to save any modified tables and records before the JVM exits. The listener is added by referencing it in the startup properties vile via the LifeCycleListener entry.
