Method Detail

initLog4j

public static void initLog4j()

Initialize logging in such a way that it checks for config changes every 10 seconds.

setup

protected void setup()

This is a hook for concrete daemons to initialize themselves suitably. Subclasses should override this to finish the job (listening on ports, etc.)

Throws:

java.io.IOException

init

public void init(java.lang.String[] arguments)
          throws java.io.IOException

Initialize the Cassandra Daemon based on the given Commons Daemon-specific arguments. To clarify, this is a hook for JSVC.

Parameters:

arguments - the arguments passed in from JSVC

Throws:

java.io.IOException

start

public void start()

Start the Cassandra Daemon, assuming that it has already been initialized via init(String[]) Hook for JSVC

stop

public void stop()

Stop the daemon, ideally in an idempotent manner. Hook for JSVC

destroy

public void destroy()

Clean up all resources obtained during the lifetime of the daemon. This is a hook for JSVC.

activate

public void activate()

A convenience method to initialize and start the daemon in one shot.

deactivate

public void deactivate()

A convenience method to stop and destroy the daemon in one shot.

stop

public static void stop(java.lang.String[] args)

main

public static void main(java.lang.String[] args)
