Class FastValueAccessMap<K,​V>

  • All Implemented Interfaces:
    java.util.Map<K,​V>
    public class FastValueAccessMap<K,​V>
extends java.lang.Object
implements java.util.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.
