Pointer to a UBreakIterator maintain a - * current position and scan over text returning the index of characters - * where boundaries occur. - * <p> - * Line boundary analysis determines where a text string can be broken - * when line-wrapping. The mechanism correctly handles punctuation and - * hyphenated words. - * <p> - * Sentence boundary analysis allows selection with correct - * interpretation of periods within numbers and abbreviations, and - * trailing punctuation marks such as quotation marks and parentheses. - * <p> - * Word boundary analysis is used by search and replace functions, as - * well as within text editing applications that allow the user to - * select words with a double click. Word selection provides correct - * interpretation of punctuation marks within and following - * words. Characters that are not part of a word, such as symbols or - * punctuation marks, have word-breaks on both sides. - * <p> - * Character boundary analysis allows users to interact with - * characters as they expect to, for example, when moving the cursor - * through a text string. Character boundary analysis provides correct - * navigation of through character strings, regardless of how the - * character is stored. For example, an accented character might be - * stored as a base character and a diacritical mark. What users - * consider to be a character can differ between languages. - * <p> - * Title boundary analysis locates all positions, - * typically starts of words, that should be set to Title Case - * when title casing the text. - * <p> - * The text boundary positions are found according to the rules - * described in Unicode Standard Annex #29, Text Boundaries, and - * Unicode Standard Annex #14, Line Breaking Properties.
