IntObjectHashMap (Netty API Reference (4.0.56.Final))

java.lang.Object
- io.netty.util.collection.IntObjectHashMap<V>

Type Parameters:

V - The value type stored in the map.

All Implemented Interfaces:

IntObjectMap<V>, java.lang.Iterable<IntObjectMap.Entry<V>>
```
public class IntObjectHashMap<V>
extends java.lang.Object
implements IntObjectMap<V>, java.lang.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 linear probing. Deletions implement compaction, so cost of remove can approach O(N) for full maps, which makes a small loadFactor recommended.
