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

Type Parameters:

K - key type

V - value type

M - map type

All Implemented Interfaces:

Map<K,V>, HistoricalMap<K,V>, HistoryManager.HistoricalElement

Direct Known Subclasses:

AbstractHistoricalSortedMap, HistoricalEnumMap, HistoricalHashMap, HistoricalLinkedHashMap
```
public abstract class AbstractHistoricalMap<K,V,M extends Map<K,V>>
extends AbstractHistorical<K,AbstractHistoricalMap.EventMap<K,V,M>>
implements HistoricalMap<K,V>
```
Map-valued historical state. The current map is always maintained, and past states of the map are obtained by applying the events between now and the requested time in reverse.

The set views returned by this class are unmodifiable.
