Class RWSConfigFactory

  • All Implemented Interfaces:
    RWSConfig

    public final class RWSConfigFactory
    extends RWSConfigManager
    This is the singleton class used to load the configuration for the OpenNMS Poller service from the poller-configuration xml file. A mapping of the configured URLs to the iplist they contain is built at init() time so as to avoid numerous file reads. 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.
