57/**
58 * The BreakIterator class implements methods for finding the location
59 * of boundaries in text. BreakIterator is an abstract base class.
60 * Instances of BreakIterator maintain a current position and scan over
61 * text returning the index of characters where boundaries occur.
62 * <p>
63 * Line boundary analysis determines where a text string can be broken
64 * when line-wrapping. The mechanism correctly handles punctuation and
65 * hyphenated words.
66 * <p>
67 * Sentence boundary analysis allows selection with correct
68 * interpretation of periods within numbers and abbreviations, and
69 * trailing punctuation marks such as quotation marks and parentheses.
70 * <p>
71 * Word boundary analysis is used by search and replace functions, as
72 * well as within text editing applications that allow the user to
73 * select words with a double click. Word selection provides correct
74 * interpretation of punctuation marks within and following
75 * words. Characters that are not part of a word, such as symbols or
76 * punctuation marks, have word-breaks on both sides.
77 * <p>
78 * Character boundary analysis allows users to interact with
79 * characters as they expect to, for example, when moving the cursor
80 * through a text string. Character boundary analysis provides correct
81 * navigation of through character strings, regardless of how the
82 * character is stored. For example, an accented character might be
83 * stored as a base character and a diacritical mark. What users
84 * consider to be a character can differ between languages.
85 * <p>
86 * The text boundary positions are found according to the rules
87 * described in Unicode Standard Annex #29, Text Boundaries, and
88 * Unicode Standard Annex #14, Line Breaking Properties. These
89 * are available at http://www.unicode.org/reports/tr14/ and
90 * http://www.unicode.org/reports/tr29/.
91 * <p>
92 * In addition to the C++ API defined in this header file, a
93 * plain C API with equivalent functionality is defined in the
94 * file ubrk.h
95 * <p>
96 * Code snippets illustrating the use of the Break Iterator APIs
97 * are available in the ICU User Guide,
98 * http://icu-project.org/userguide/boundaryAnalysis.html
99 * and in the sample program icu/source/samples/break/break.cpp
