hashCode</H3>
<PRE>
public int <B>hashCode</B>()</PRE>
<DL>
<DD>Returns the hash code value for this <code>CompositeData</code> instance. 
 <p>
 The hash code of a <code>CompositeData</code> instance is the sum of the hash codes
 of all elements of information used in <code>equals</code> comparisons 
 (ie: its <i>composite type</i> and all the item values). 
 <p>
 This ensures that <code> t1.equals(t2) </code> implies that <code> t1.hashCode()==t2.hashCode() </code> 
 for any two <code>CompositeData</code> instances <code>t1</code> and <code>t2</code>, 
 as required by the general contract of the method

 <code>Object.hashCode</code> </a>.

<DL>
<DD>Returns a string representation of this <code>CompositeData</code> instance. 
 <p>
 The string representation consists of the name of the implementing class, 
 the string representation of the composite type of this instance, and the string representation of the contents
 (ie list the itemName=itemValue mappings).
