Class HashBlockEntry

class HashBlockEntry
extends java.lang.Object

HashBlock entry. It associates a key to a value, keeping also track of the hashcode so that it doesn't have to be recomputed each time. The projection between the hashcode space and the main array of the HashBlock may result result in conflicts: different keys may have the same hashcode, and hashcode may project in the same place in the main array. That's why there is a next pointer in the entry, it allows to have collision lists, ans the hashcode is there because in one given collision list, several hashcodes may be present.
