| 56 * The BreakIterator class implements methods for finding the location | |
| 57 * of boundaries in text. BreakIterator is an abstract base class. | |
| 58 * Instances of BreakIterator maintain a current position and scan over | |
| 59 * text returning the index of characters where boundaries occur. | |
| 60 * <p> | |
| 61 * Line boundary analysis determines where a text string can be broken | |
| 62 * when line-wrapping. The mechanism correctly handles punctuation and | |
| 63 * hyphenated words. | |
| 64 * <p> | |
| 65 * Sentence boundary analysis allows selection with correct | |
| 66 * interpretation of periods within numbers and abbreviations, and | |
| 67 * trailing punctuation marks such as quotation marks and parentheses. | |
| 68 * <p> | |
| 69 * Word boundary analysis is used by search and replace functions, as | |
| 70 * well as within text editing applications that allow the user to | |
| 71 * select words with a double click. Word selection provides correct | |
| 72 * interpretation of punctuation marks within and following | |
| 73 * words. Characters that are not part of a word, such as symbols or | |
| 74 * punctuation marks, have word-breaks on both sides. | |
| 75 * <p> | |
| 76 * Character boundary analysis allows users to interact with | |
| 77 * characters as they expect to, for example, when moving the cursor | |
| 78 * through a text string. Character boundary analysis provides correct | |
| 79 * navigation of through character strings, regardless of how the | |
| 80 * character is stored. For example, an accented character might be | |
| 81 * stored as a base character and a diacritical mark. What users | |
| 82 * consider to be a character can differ between languages. | |
| 83 * <p> | |
| 84 * The text boundary positions are found according to the rules | |
| 85 * described in Unicode Standard Annex #29, Text Boundaries, and | |
| 86 * Unicode Standard Annex #14, Line Breaking Properties. These | |
| 87 * are available at http://www.unicode.org/reports/tr14/ and | |
| 88 * http://www.unicode.org/reports/tr29/. | |
| 89 * <p> | |
| 90 * In addition to the C++ API defined in this header file, a | |
| 91 * plain C API with equivalent functionality is defined in the | |
| 92 * file ubrk.h | |
| 93 * <p> | |
| 94 * Code snippets illustrating the use of the Break Iterator APIs | |
| 95 * are available in the ICU User Guide, | |
| 96 * http://icu-project.org/userguide/boundaryAnalysis.html | |
| 97 * and in the sample program icu/source/samples/break/break.cpp | |
