virtual int32_t last() override

Sets the current iteration position to the end of the text.

virtual int32_t preceding(int32_t offset) override

Sets the iterator to refer to the last boundary position before the specified position.

RuleBasedBreakIterator(const RuleBasedBreakIterator &that)

Copy constructor.

virtual void adoptText(CharacterIterator *newText) override

virtual int32_t previous() override

Moves the iterator backwards, to the last boundary preceding this one.

RuleBasedBreakIterator(UDataMemory *image, UErrorCode &status)

This constructor uses the udata interface to create a BreakIterator whose internal tables live in a m...

virtual int32_t next(int32_t n) override

Advances the iterator either forward or backward the specified number of steps.

virtual CharacterIterator & getText() const override

virtual const UnicodeString & getRules() const

Returns the description used to create this iterator.
