+/**
+* The CollationElementIterator class is used as an iterator to walk through     
+* each character of an international string. Use the iterator to return the
+* ordering priority of the positioned character. The ordering priority of a 
+* character, which we refer to as a key, defines how a character is collated in 
+* the given collation object.
+* For example, consider the following in Spanish:
+* <pre>
+*        "ca" -> the first key is key('c') and second key is key('a').
+*        "cha" -> the first key is key('ch') and second key is key('a').</pre>
+* And in German,
+* <pre> \htmlonly       "&#x00E6;b"-> the first key is key('a'), the second key is key('e'), and
+*        the third key is key('b'). \endhtmlonly </pre>
+* The key of a character, is an integer composed of primary order(short),
+* secondary order(char), and tertiary order(char). Java strictly defines the 
+* size and signedness of its primitive data types. Therefore, the static
+* functions primaryOrder(), secondaryOrder(), and tertiaryOrder() return 
+* int32_t to ensure the correctness of the key value.
+* <p>Example of the iterator usage: (without error checking)
+* <pre>
+* \code
+*   void CollationElementIterator_Example()
+*   {
+*       UnicodeString str = "This is a test";
+*       UErrorCode success = U_ZERO_ERROR;
+*       RuleBasedCollator* rbc =
+*           (RuleBasedCollator*) RuleBasedCollator::createInstance(success);
+*       CollationElementIterator* c =
+*           rbc->createCollationElementIterator( str );
+*       int32_t order = c->next(success);
+*       c->reset();
+*       order = c->previous(success);
+*       delete c;
+*       delete rbc;
+*   }
+* \endcode
+* </pre>
+* <p>
+* CollationElementIterator::next returns the collation order of the next
+* character based on the comparison level of the collator. 
+* CollationElementIterator::previous returns the collation order of the 
+* previous character based on the comparison level of the collator. 
+* The Collation Element Iterator moves only in one direction between calls to
+* CollationElementIterator::reset. That is, CollationElementIterator::next() 
+* and CollationElementIterator::previous can not be inter-used. Whenever 
+* CollationElementIterator::previous is to be called after 
+* CollationElementIterator::next() or vice versa, 
+* CollationElementIterator::reset has to be called first to reset the status, 
+* shifting pointers to either the end or the start of the string. Hence at the 
+* next call of CollationElementIterator::previous or 
+* CollationElementIterator::next(), the first or last collation order will be 
+* returned. 
+* If a change of direction is done without a CollationElementIterator::reset(), 
+* the result is undefined.
+* The result of a forward iterate (CollationElementIterator::next) and 
+* reversed result of the backward iterate (CollationElementIterator::previous) 
+* on the same string are equivalent, if collation orders with the value 
+* UCOL_IGNORABLE are ignored.
+* Character based on the comparison level of the collator.  A collation order 
+* consists of primary order, secondary order and tertiary order.  The data 
+* type of the collation order is <strong>t_int32</strong>. 
+*
+* Note, CollationElementIterator should not be subclassed.
+* @see     Collator
+* @see     RuleBasedCollator
