The default implementations of this method is an <a

relation</a>:
<ul>
<li>It is reflexive: for any instance <code>x</code> of type <code>Any</code>,
<code>x.equals(x)</code> should return <code>true</code>.</li>
<li>It is symmetric: for any instances <code>x</code> and <code>y</code> of type
<code>Any</code>, <code>x.equals(y)</code> should return <code>true</code> if and only
if <code>y.equals(x)</code> returns <code>true</code>.</li>
<li>It is transitive: for any instances
<code>x</code>, <code>y</code>, and <code>z</code> of type <code>AnyRef</code>
if <code>x.equals(y)</code> returns <code>true</code> and
<code>y.equals(z)</code> returns
<code>true</code>, then <code>x.equals(z)</code> should return <code>true</code>.</li>
</ul>
</p></p><p><p>
If you override this method, you should verify that
your implementation remains an equivalence relation.
Additionally, when overriding this method it is often necessary to
override <code>hashCode</code> to ensure that objects that are
"equal" (<code>o1.equals(o2)</code> returns <code>true</code>)
hash to the same <a href="Int.html"><code>Int</code></a>
(<code>o1.hashCode.equals(o2.hashCode)</code>).

<div class="comment cmt"><p>Returns a hash code value for the object.</p><p><p>
The default hashing algorithm is platform dependent.</p><p>Note that it is allowed for two objects to have identical hash
codes (<code>o1.hashCode.equals(o2.hashCode)</code>) yet not be
equal (<code>o1.equals(o2)</code> returns <code>false</code>). A
degenerate implementation could always return <code>0</code>.
However, it is required that if two objects are equal
(<code>o1.equals(o2)</code> returns <code>true</code>) that they
have identical hash codes
(<code>o1.hashCode.equals(o2.hashCode)</code>). Therefore, when
overriding this method, be sure to verify that the behavior is
consistent with the <code>equals</code> method.
