Class SnmpInterfacePollerConfigFactory

java.lang.Object

org.opennms.netmgt.config.SnmpInterfacePollerConfigManager

org.opennms.netmgt.config.SnmpInterfacePollerConfigFactory

All Implemented Interfaces:

SnmpInterfacePollerConfig

public final class SnmpInterfacePollerConfigFactory
extends SnmpInterfacePollerConfigManager

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 IP list 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.
