          org.opennms.netmgt.rtc.datablock.RTCHashMap

All Implemented Interfaces:

java.lang.Cloneable, java.util.Map, java.io.Serializable

public class RTCHashMap

extends java.util.HashMap

The RTCHashMap has either a nodeid or a nodeid/ip as key and provides convenience methods to add and remove 'RTCNodes' with these values - each key points to a list of 'RTCNode's
