public class Int2IntConcurrentOpenHashMap extends AbstractInt2IntMap implements Int2IntConcurrentMap, ITrimmable
A TypeSpecific ConcurrentHashMap implementation that is based on Guavas approach and backing array implementations. Like Guavas implementation this solution can be accessed by multiple threads, but it is not as flexible as Javas implementation. The concurrencyLevel decides how many pools exist, and each pool can be accessed by 1 thread for writing and as many threads for reading. Though it is ill adviced to iterate over the collection using the Iterator if the Map is written to. Keep that in mind.

      public int computeIntIfAbsentNonDefault(int key, IntUnaryOperator mappingFunction)
      Beschreibung aus Schnittstelle kopiert: Int2IntMap
      A Type Specific computeIfAbsent method to reduce boxing/unboxing If the generated value equals the getDefaultReturnValue it will simply not insert it since that is treated as "null". A "Null Value" will be treated as "Do not insert/remove" based on how the Java has specified it.

      public int supplyIntIfAbsentNonDefault(int key, IntSupplier valueProvider)
      Beschreibung aus Schnittstelle kopiert: Int2IntMap
      A Supplier based computeIfAbsent function to fill the most used usecase of this function If the generated value equals the getDefaultReturnValue it will simply not insert it since that is treated as "null". A "Null Value" will be treated as "Do not insert/remove" based on how the Java has specified it.
