Class FastValueAccessMap<K,V>

java.lang.Object

fr.gouv.vitam.worker.core.utils.FastValueAccessMap<K,V>

All Implemented Interfaces:

Map<K,V>

public class FastValueAccessMap<K,V>
extends Object
implements Map<K,V>

Deprecated.

Hacky implementation for HashMap with fast "containsKey" O(1) method. Refactoring existing code is too risky and requires a full rewrite of ExtractSedaActionHandler and ArchiveUnitListener classes. Entry values are stored in a dedicated Map of Key to Integer Counter that tracks the values and their reference count. Null values are wrapped over a NULL_VALUE_OBJ object because HashMap implementation does not support nulls are keys. Sorry for the inconvenience.
