Class WmiPeerFactory

java.lang.Object

org.opennms.netmgt.config.WmiPeerFactory

public class WmiPeerFactory
extends Object

This class is the main repository for WMI configuration information used by the capabilities daemon. When this class is loaded it reads the WMI configuration into memory, and uses the configuration to find the WmiAgentConfig objects for specific addresses. If an address cannot be located in the configuration then a default peer instance is returned to the caller. 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.
