Hash

public static interface Hash.Strategy<K>

A generic hash strategy.

Custom hash structures (e.g., com.uwyn.jhighlight.fastutil.objects.ObjectOpenCustomHashSet) allow to hash objects using arbitrary functions, a typical example being that of arrays. Of course, one has to compare objects for equality consistently with the chosen function. A hash strategy, thus, specifies an equality method and a hash function, with the obvious property that equal objects must have the same hash code.

If your custom collection must be able to contain null, then your strategy must be able to handle null, too.
