Class ShortIntScatterMap

java.lang.Object

           value="KTypeVTypeScatterMap.java")
public class ShortIntScatterMap
extends ShortIntHashMap
```
Same as ShortIntHashMap but does not implement per-instance key mixing strategy and uses a simpler (faster) bit distribution function.
Note: read about important differences between hash and scatter sets.

```
protected int hashKey(short key)
```
    Description copied from class: ShortIntHashMap
    
    Returns a hash code for the given key.
    The default implementation mixes the hash of the key with ShortIntHashMap.keyMixer to differentiate hash order of keys between hash containers. Helps alleviate problems resulting from linear conflict resolution in open addressing.
    
    The output from this function should evenly distribute keys across the entire integer range.

```
    Creates a hash map from two index-aligned arrays of key-value pairs.
