Class DefaultResourceDao

java.lang.Object

org.opennms.netmgt.dao.support.DefaultResourceDao

All Implemented Interfaces:

ResourceDao, org.springframework.beans.factory.InitializingBean

public class DefaultResourceDao
extends Object
implements ResourceDao, org.springframework.beans.factory.InitializingBean

Retrieves and enumerates elements from the resource tree. This class is responsible for maintaining the list of resource types and coordinating amongst these. All resource type specific logic should be contained in the resource type implementations rather than this class.
