* Returns the hash code value for this <code>CompositeDataSupport</code> instance.
*
* <p>The hash code of a <code>CompositeDataSupport</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>CompositeDataSupport</code> instances
* <code>t1</code> and <code>t2</code>, as required by the general contract of the method {@link
* Object#hashCode() Object.hashCode()}.
*
* <p>Each item value's hash code is added to the returned hash code. If an item value is an
* array, its hash code is obtained as if by calling the {@link
* j86.java.util.Arrays#deepHashCode(Object[]) deepHashCode} method for arrays of object reference
* types or the appropriate overloading of {@code Arrays.hashCode(e)} for arrays of primitive
* types.
