org.opennms.netmgt.eventd.datablock.EventMaskValueList

All Implemented Interfaces:

Serializable, Cloneable, Iterable<String>, Collection<String>, List<String>, RandomAccess

public class EventMaskValueList
extends ArrayList<String>

The maskelement values in a 'EventKey' are stored in this ArrayList subclass This list is pretty much constant once it constructed - so the hashcode is evaluated once at construction and reused(if new values are added or values changed, hashcode is re-evaluated)
