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 Slovak and in traditional Spanish collation: * <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 phonebook collation, * <pre> \htmlonly "æb"-> 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> * The method next() returns the collation order of the next character based on * the comparison level of the collator. The method 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 reset(), setOffset(), or setText(). That is, next() * and previous() can not be inter-used. Whenever previous() is to be called after * next() or vice versa, reset(), setOffset() or setText() has to be called first * to reset the status, shifting pointers to either the end or the start of * the string (reset() or setText()), or the specified position (setOffset()). * Hence at the next call of next() or previous(), the first or last collation order, * or collation order at the spefcifieid position will be returned. If a change of * direction is done without one of these calls, the result is undefined. * <p> * The result of a forward iterate (next()) and reversed result of the backward * iterate (previous()) on the same string are equivalent, if collation orders * with the value 0 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>int32_t</strong>. * * Note, CollationElementIterator should not be subclassed. * @see Collator * @see RuleBasedCollator * @version 1.8 Jan 16 2001 */ class U_I18N_API CollationElementIterator U_FINAL : public UObject { public: // CollationElementIterator public data member ------------------------------ enum { /** * NULLORDER indicates that an error has occured while processing * @stable ICU 2.0 */ NULLORDER = (int32_t)0xffffffff }; // CollationElementIterator public constructor/destructor ------------------- /** * Copy constructor. * * @param other the object to be copied from * @stable ICU 2.0 */ CollationElementIterator(const CollationElementIterator& other); /** * Destructor * @stable ICU 2.0 */ virtual ~CollationElementIterator(); // CollationElementIterator public methods ---------------------------------- /** * Returns true if "other" is the same as "this" * * @param other the object to be compared * @return true if "other" is the same as "this" * @stable ICU 2.0 */ UBool operator==(const CollationElementIterator& other) const; /** * Returns true if "other" is not the same as "this". * * @param other the object to be compared * @return true if "other" is not the same as "this" * @stable ICU 2.0 */ UBool operator!=(const CollationElementIterator& other) const; /** * Resets the cursor to the beginning of the string. * @stable ICU 2.0 */ void reset(void); /** * Gets the ordering priority of the next character in the string. * @param status the error code status. * @return the next character's ordering. otherwise returns NULLORDER if an * error has occured or if the end of string has been reached * @stable ICU 2.0 */ int32_t next(UErrorCode& status); /** * Get the ordering priority of the previous collation element in the string. * @param status the error code status. * @return the previous element's ordering. otherwise returns NULLORDER if an * error has occured or if the start of string has been reached * @stable ICU 2.0 */ int32_t previous(UErrorCode& status); /** * Gets the primary order of a collation order. * @param order the collation order * @return the primary order of a collation order. * @stable ICU 2.0 */ static inline int32_t primaryOrder(int32_t order); /** * Gets the secondary order of a collation order. * @param order the collation order * @return the secondary order of a collation order. * @stable ICU 2.0 */ static inline int32_t secondaryOrder(int32_t order); /** * Gets the tertiary order of a collation order. * @param order the collation order * @return the tertiary order of a collation order. * @stable ICU 2.0 */ static inline int32_t tertiaryOrder(int32_t order); /** * Return the maximum length of any expansion sequences that end with the * specified comparison order. * @param order a collation order returned by previous or next. * @return maximum size of the expansion sequences ending with the collation * element or 1 if collation element does not occur at the end of any * expansion sequence * @stable ICU 2.0 */ int32_t getMaxExpansion(int32_t order) const; /** * Gets the comparison order in the desired strength.
