d-tagdata jd-tagdescr"><p>Returns an integer hash code for this object. By contract, any two
 objects for which <code><a href="../../../../../../reference/java/lang/Object.html#equals(java.lang.Object)">equals(Object)</a></code> returns <code>true</code> must return
 the same hash code value. This means that subclasses of <code>Object</code>
 usually override both methods or neither method.

 <p>Note that hash values must not change over time unless information used in equals
 comparisons also changes.
