-/**
- * This class is a convenience method to sequentially calculate hash code of the
- * object based on the field values. The result depends on the order of elements
- * appended. The exact formula is the same as for
- * <code>java.util.List.hashCode</code>.
- * 
- * If you need order independent hash code just summate, multiply or XOR all
- * elements.
- * 
- * <p>
- * Suppose we have class:
- * 
- * <pre><code>
- * class Thing {
- *     long id;
- *     String name;
- *     float weight;
- * }
- * </code></pre>
- * 
- * The hash code calculation can be expressed in 2 forms.
- * 
- * <p>
- * For maximum performance:
- * 
- * <pre><code>
- * public int hashCode() {
- *     int hashCode = HashCode.EMPTY_HASH_CODE;
- *     hashCode = HashCode.combine(hashCode, id);
- *     hashCode = HashCode.combine(hashCode, name);
- *     hashCode = HashCode.combine(hashCode, weight);
- *     return hashCode;
- * }
- * </code></pre>
- * 
- * <p>
- * For convenience: <code><pre>
- * public int hashCode() {
- *     return new HashCode().append(id).append(name).append(weight).hashCode();
- * }
- * </code></pre>
