-* 12/10/99    aliu        Ported Thai collation support from Java.
-* 01/25/01    swquek      Modified into a C++ wrapper calling C APIs (ucoliter.h)
-* 02/19/01    swquek      Removed CollationElementsIterator() since it is

-/**
-* 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
