HistoricalEnumMap (OpenTrafficSim core classes 1.6.0 API)

java.lang.Object
- org.opentrafficsim.core.perception.AbstractHistorical<K,AbstractHistoricalMap.EventMap<K,V,M>>
- - org.opentrafficsim.core.perception.collections.AbstractHistoricalMap<K,V,EnumMap<K,V>>
  - - org.opentrafficsim.core.perception.collections.HistoricalEnumMap<K,V>

Type Parameters:

K - key type

V - value type

All Implemented Interfaces:

Map<K,V>, HistoricalMap<K,V>, HistoryManager.HistoricalElement
```
public class HistoricalEnumMap<K extends Enum<K>,V>
extends AbstractHistoricalMap<K,V,EnumMap<K,V>>
```
EnumMap-valued historical state. The current enum map is always maintained, and past states of the enum map are obtained by applying the events between now and the requested time in reverse.

The set views returned by this class are unmodifiable.
