HistoricalLinkedHashMap (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,LinkedHashMap<K,V>>
  - - org.opentrafficsim.core.perception.collections.HistoricalLinkedHashMap<K,V>

Type Parameters:

K - key type

V - value type

All Implemented Interfaces:

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

The set views returned by this class are unmodifiable.
