Method Detail

getInstanceForTesting

public static CassandraDaemon getInstanceForTesting()

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.)

initializeNativeTransport

public void initializeNativeTransport()

startNativeTransport

public void startNativeTransport()

completeSetup

public void completeSetup()

setupCompleted

public boolean setupCompleted()

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 / Procrun

public void destroyNativeTransport()
                            throws java.lang.InterruptedException

Throws:

java.lang.InterruptedException

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.
