-/**
- *
- * Collation keys are generated by the Collator class.  Use the CollationKey objects
- * instead of Collator to compare strings multiple times.  A CollationKey
- * preprocesses the comparison information from the Collator object to
- * make the comparison faster.  If you are not going to comparing strings
- * multiple times, then using the Collator object is generally faster,
- * since it only processes as much of the string as needed to make a
- * comparison.
- * <p> For example (with strength == tertiary)
- * <p>When comparing "Abernathy" to "Baggins-Smythworthy", Collator
- * only needs to process a couple of characters, while a comparison
- * with CollationKeys will process all of the characters.  On the other hand,
- * if you are doing a sort of a number of fields, it is much faster to use
- * CollationKeys, since you will be comparing strings multiple times.
- * <p>Typical use of CollationKeys are in databases, where you store a CollationKey
- * in a hidden field, and use it for sorting or indexing.
- *
- * <p>Example of use:
- * <pre>
- * \code
- *     UErrorCode success = U_ZERO_ERROR;
- *     Collator* myCollator = Collator::createInstance(success);
- *     CollationKey* keys = new CollationKey [3];
- *     myCollator->getCollationKey("Tom", keys[0], success );
- *     myCollator->getCollationKey("Dick", keys[1], success );
- *     myCollator->getCollationKey("Harry", keys[2], success );
- *
- *     // Inside body of sort routine, compare keys this way:
- *     CollationKey tmp;
- *     if(keys[0].compareTo( keys[1] ) > 0 ) {
- *         tmp = keys[0]; keys[0] = keys[1]; keys[1] = tmp;
- *     }
- *     //...
- * \endcode
- * </pre>
- * <p>Because Collator::compare()'s algorithm is complex, it is faster to sort
- * long lists of words by retrieving collation keys with Collator::getCollationKey().
- * You can then cache the collation keys and compare them using CollationKey::compareTo().
- * <p>
- * <strong>Note:</strong> <code>Collator</code>s with different Locale,
- * CollationStrength and DecompositionMode settings will return different
- * CollationKeys for the same set of strings. Locales have specific
- * collation rules, and the way in which secondary and tertiary differences
- * are taken into account, for example, will result in different CollationKeys
- * for same strings.
- * <p>
