public final class DhcpdConfigFactory
extends Object

This is the singleton class used to load the configuration for the OpenNMS DHCP client deamon from the dhcpd-configuration xml file. Note: Users of this class should make sure the init() is called before calling any other method to ensure the config is loaded before accessing other convenience methods.
