java.lang.Object

java.util.AbstractMap<K,V>

java.util.concurrent.ConcurrentHashMap<java.lang.String,AlarmQueue.AlarmToQueue>

alma.acs.alarmsystem.source.AlarmQueue

All Implemented Interfaces:

java.io.Serializable, java.util.concurrent.ConcurrentMap<java.lang.String,AlarmQueue.AlarmToQueue>, java.util.Map<java.lang.String,AlarmQueue.AlarmToQueue>

public class AlarmQueue
extends java.util.concurrent.ConcurrentHashMap<java.lang.String,AlarmQueue.AlarmToQueue>

A queue of alarms.

The alarms are stored in a map because we want to storein the vector are ordered following their arrival time i.e. the oldest item is in the head.

The class is thread safe.

For the implementation a Set would have been enough but the ConcurrentHashMap is thread safe and there should not be big perfromance difference between this and a concrete Set.
