Class CollectionResourceWrapper

java.lang.Object

org.opennms.netmgt.threshd.CollectionResourceWrapper

public class CollectionResourceWrapper
extends Object

CollectionResourceWrapper class.

Wraps a CollectionResource with some methods and caching for the efficient application of thresholds (without pulling thresholding code into CollectionResource itself) A fresh instance should be created for each collection cycle (assumptions are made based on that premise)
