BreakIterator is an abstract base class. 64 * Instances of BreakIterator maintain a current position and scan over 65 * text returning the index of characters where boundaries occur. 66 * <p> 67 * Line boundary analysis determines where a text string can be broken 68 * when line-wrapping. The mechanism correctly handles punctuation and 69 * hyphenated words. 70 * <p> 71 * Sentence boundary analysis allows selection with correct 72 * interpretation of periods within numbers and abbreviations, and 73 * trailing punctuation marks such as quotation marks and parentheses. 74 * <p> 75 * Word boundary analysis is used by search and replace functions, as 76 * well as within text editing applications that allow the user to 77 * select words with a double click. Word selection provides correct 78 * interpretation of punctuation marks within and following 79 * words. Characters that are not part of a word, such as symbols or 80 * punctuation marks, have word-breaks on both sides. 81 * <p> 82 * Character boundary analysis allows users to interact with 83 * characters as they expect to, for example, when moving the cursor 84 * through a text string. Character boundary analysis provides correct 85 * navigation of through character strings, regardless of how the 86 * character is stored. For example, an accented character might be 87 * stored as a base character and a diacritical mark. What users 88 * consider to be a character can differ between languages. 89 * <p> 90 * The text boundary positions are found according to the rules 91 * described in Unicode Standard Annex #29, Text Boundaries, and 92 * Unicode Standard Annex #14, Line Breaking Properties. These 93 * are available at http://www.unicode.org/reports/tr14/ and 94 * http://www.unicode.org/reports/tr29/. 95 * <p> 96 * In addition to the C++ API defined in this header file, a 97 * plain C API with equivalent functionality is defined in the 98 * file ubrk.h 99 * <p> 100 * Code snippets illustrating the use of the Break Iterator APIs 101 * are available in the ICU User Guide, 102 * https://unicode-org.github.io/icu/userguide/boundaryanalysis/ 103 * and in the sample program icu/source/samples/break/break.cpp 104 * 105 */ 106 class U_COMMON_API BreakIterator : public UObject { 107 public: 108 /** 109 * destructor 110 * @stable ICU 2.0 111 */ 112 virtual ~BreakIterator(); 113 114 /** 115 * Return true if another object is semantically equal to this 116 * one.
