io.netty.util.collection

Class IntObjectHashMap<V>

java.lang.Object

io.netty.util.collection.IntObjectHashMap<V>

Type Parameters:

V - The value type stored in the map.

All Implemented Interfaces:

IntObjectMap<V>, Iterable<IntObjectMap.Entry<V>>

public class IntObjectHashMap<V>
extends Object
implements IntObjectMap<V>, Iterable<IntObjectMap.Entry<V>>

A hash map implementation of IntObjectMap that uses open addressing for keys. To minimize the memory footprint, this class uses open addressing rather than chaining. Collisions are resolved using double hashing.
