public class LongCharScatterMap
extends LongCharHashMap
```
Same as LongCharHashMap 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.

    Description copied from class: LongCharHashMap
    
    Returns a hash code for the given key.
    The default implementation mixes the hash of the key with LongCharHashMap.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.
