Under the current scheme, anyone who want to use an AtomicInteger
with value-based semantics as a key in a hash table, only has
to say "get()"
table.put(myAtomicInteger.get(), something); // value-based
versus, for identity-based, table.put(myAtomicInteger, something);
Autoboxing takes care of the rest in the value case. And there's no
risk in not finding it again in case the variable changes value.
Similarly for contexts using Comparable.
What could be nicer? :-)
