Method Detail

main

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

Main entry point for the native daemon

Parameters:

argv - "Command-line" parameters

buildOptionsList

protected org.apache.commons.cli.Options buildOptionsList()

Description copied from class: BaseDaemon

Creates the "master" list of options which the daemon implementation knows about. Implementations should override this method if they need param parsing.

Overrides:

buildOptionsList in class BaseDaemon

Returns:

org.apache.commons.cli.Options instance populated with options or null if no options

onStartup

protected int onStartup(org.apache.commons.cli.CommandLine commandLine)

Description copied from class: BaseDaemon

Lifecycle method called when the daemon implementation is started. This method _must_ return otherwise the daemon will appear to hang at startup. This implies that all "real" work needs to be done in a separate thread.

Specified by:

onStartup in class BaseDaemon

Parameters:

commandLine - Parsed params, if present. Otherwise null.

Returns:

int indicates status where BaseDaemon.SUCCESS indicates success and any other number indicates failure

onShutdown

protected int onShutdown(boolean breakFromUser)

Description copied from class: BaseDaemon

Lifecycle method called when the daemon implementation is stopped.

Specified by:

onShutdown in class BaseDaemon

Parameters:

breakFromUser - True if the user sent a Ctrl-C

Returns:

int indicates status where BaseDaemon.SUCCESS indicates success and any other number indicates an error
