Type Parameters:

T - the type of elements maintained by this Collection

All Implemented Interfaces:

java.util.concurrent.ConcurrentMap<T,java.lang.Integer>, java.util.function.ToIntFunction<T>, java.util.Map<T,java.lang.Integer>, Object2IntFunction<T>, Object2IntConcurrentMap<T>, Object2IntMap<T>, ITrimmable

public class Object2IntConcurrentOpenHashMap<T>
extends AbstractObject2IntMap<T>
implements Object2IntConcurrentMap<T>, 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.
