start

public final void start()
                 throws ConfigurationException

This implementation can be invoked multiple times. ServiceBase class maintains internal started flag to ensure that startInternal() method is invoked only once. The naming bus invokes this method every time before returning service from get() method.

stopInternal

protected abstract void stopInternal()
                              throws ConfigurationException

Throws:

ConfigurationException

stop

public final void stop()
                throws ConfigurationException

Invokes stopInternal if all dependent services has been stopped. Otherwise goes into "stoppable" state. When stops, also stops all stoppable previous services.

Specified by:

stop in interface Component

Throws:

ConfigurationException
