Class ThreshdConfigFactory

java.lang.Object

org.opennms.netmgt.config.ThreshdConfigManager

org.opennms.netmgt.config.ThreshdConfigFactory

public final class ThreshdConfigFactory
extends ThreshdConfigManager

This is the singleton class used to load the configuration for the OpenNMS Thresholding Daemon from the threshd-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.
