Class ApplicationShutdownHook

java.lang.Object

io.sbk.utils.ApplicationShutdownHook

public final class ApplicationShutdownHook
extends Object

Registers a bounded JVM shutdown hook for an SBK application.

The actual application cleanup runs on a separate daemon thread. The JVM hook waits for it only for a bounded interval, ensuring that a blocked storage driver, SSH operation, logger, or network server cannot prevent the process from terminating after SIGINT or SIGTERM.

Method Details

register

public static Thread register(String applicationName,
 Runnable cleanup)

Registers a shutdown hook for an application benchmark.

Parameters:

applicationName - application name used in lifecycle messages

cleanup - cleanup operation, normally benchmark.stop()

Returns:

the registered hook, which can be removed after normal completion

remove

public static void remove(Thread hook)

Removes a previously registered hook after normal application shutdown.

If JVM shutdown has already started, hook removal is no longer legal; this method deliberately ignores that race because the hook is already performing the requested cleanup.

Parameters:

hook - hook returned by register(String, Runnable)
