Class HistoricalTreeMap<K,V>

java.lang.Object

org.opentrafficsim.core.perception.AbstractHistorical<K,AbstractHistoricalMap.EventMap<K,V,M>>

org.opentrafficsim.core.perception.collections.AbstractHistoricalMap<K,V,M>

org.opentrafficsim.core.perception.collections.AbstractHistoricalNavigableMap<K,V,TreeMap<K,V>>

org.opentrafficsim.core.perception.collections.HistoricalTreeMap<K,V>

Type Parameters:

K - key type

V - value type

All Implemented Interfaces:

Map<K,V>, NavigableMap<K,V>, SortedMap<K,V>, HistoricalMap<K,V>, HistoricalNavigableMap<K,V>, HistoricalSortedMap<K,V>, HistoryManager.HistoricalElement

public class HistoricalTreeMap<K,V>
extends AbstractHistoricalNavigableMap<K,V,TreeMap<K,V>>

TreeMap-valued historical state. The current tree map is always maintained, and past states of the tree map are obtained by applying the events between now and the requested time in reverse.

The set views returned by this class are unmodifiable.
