Class AmiPeerFactory

java.lang.Object

org.opennms.netmgt.config.AmiPeerFactory

public class AmiPeerFactory
extends java.lang.Object

This class is the main repository for AMI configuration information used by the capabilities daemon. When this class is loaded it reads the AMI configuration into memory, and uses the configuration to find the AmiAgentConfig 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.
