Class RTCHashMap

java.lang.Object

org.opennms.netmgt.rtc.datablock.RTCHashMap

public class RTCHashMap
extends Object

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
