int hash = 7;<BR>
hash = 29 * hash + System.identityHashCode(k);<BR>
hash = 29 * hash + k.getClass().hashCode();<BR>
</CODE>

<p>
Standard hashCode calculation for EQUALITY based references, where k
is the referent:
</p>
<BR><CODE>
int hash = 7;<BR>
hash = 29 * hash + k.hashCode();<BR>
hash = 29 * hash + k.getClass().hashCode();<BR>
</CODE>
<BR>
<p>
The hash must be calculated during construction and if the reference is
cleared, the recorded hashCode returned. While the referent remains
reachable the hashCode must be calculated each time.
