-/**
- * The BreakIterator class implements methods for finding the location
- * of boundaries in text. BreakIterator is an abstract base class.
- * Instances of BreakIterator 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>
- * 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.  These
- * are available at http://www.unicode.org/reports/tr14/ and
- * http://www.unicode.org/reports/tr29/.
- * <p>
- * In addition to the C++ API defined in this header file, a
- * plain C API with equivalent functionality is defined in the
- * file ubrk.h
- * <p>
- * Code snippets illustrating the use of the Break Iterator APIs
- * are available in the ICU User Guide,
- * http://icu-project.org/userguide/boundaryAnalysis.html
- * and in the sample program icu/source/samples/break/break.cpp
