public class UnifiedMapWithHashingStrategy<K,V>
extends AbstractMutableMap<K,V>
implements Externalizable, BatchIterable<V>
UnifiedMapWithHashingStrategy stores key/value pairs in a single array, where alternate slots are keys and values.
This is nicer to CPU caches as consecutive memory addresses are very cheap to access. Entry objects are not stored in the
table like in java.util.HashMap. Instead of trying to deal with collisions in the main array using Entry objects,
we put a special object in the key slot and put a regular Object[] in the value slot. The array contains the key value
pairs in consecutive slots, just like the main array, but it's a linear list with no hashing.
The difference between UnifiedMap and UnifiedMapWithHashingStrategy is that a HashingStrategy based UnifiedMap does not rely on the hashCode or equality of the object at the key, but instead relies on a HashingStrategy implementation provided by a developer to compute the hashCode and equals for the objects stored in the map.

getFirst
Description copied from interface:RichIterable
Returns the first element of an iterable. In the case of a List it is the element at the first index. In the case of any other Collection, it is the first element that would be returned during an iteration. If the iterable is empty, null is returned. If null is a valid element of the container, then a developer would need to check to see if the iterable is empty to validate that a null result was not due to the container being empty.The order of Sets are not guaranteed (except for TreeSets and other Ordered Set implementations), so if you use this method, the first element could be any element from the Set.
