138 | This String class provides base functionality for C++ like Unicode |
139 | character array handling. The advantage of this class is that it |
140 | handles all the memory management for you - and it does it |
141 | more efficiently. If you assign a string to another string, the |
142 | data of both strings are shared (without any copy operation or |
143 | memory allocation) as long as you do not change the string. This class |
144 | also stores the length of the string, so that many operations are |
145 | faster than the C-str-functions. |
146 | |
147 | This class provides only readonly string handling. So you could create |
148 | a string and you could only query the content from this string. |
149 | It provides also functionality to change the string, but this results |
150 | in every case in a new string instance (in the most cases with a |
151 | memory allocation). You don't have functionality to change the |
152 | content of the string. If you want to change the string content, then |
153 | you should use the OStringBuffer class, which provides these |
154 | functionalities and avoids too much memory allocation. |
155 | |
156 | The design of this class is similar to the string classes in Java so |
157 | less people should have understanding problems when they use this class. |

2998 | See Chapter 3 of The Unicode Standard 5.0 (Addison--Wesley, 2006) for |

3000 | |
3001 | This string is interpreted as a sequence of zero or more UTF-16 code |
3002 | units. For each index into this sequence (from zero to one less than |
3003 | the length of the sequence, inclusive), a code point represented |
3004 | starting at the given index is computed as follows: |
3005 | |
3006 | - If the UTF-16 code unit addressed by the index constitutes a |
3007 | well-formed UTF-16 code unit sequence, the computed code point is the |
3008 | scalar value encoded by that UTF-16 code unit sequence. |
3009 | |
3010 | - Otherwise, if the index is at least two UTF-16 code units away from |
3011 | the end of the sequence, and the sequence of two UTF-16 code units |
3012 | addressed by the index constitutes a well-formed UTF-16 code unit |
3013 | sequence, the computed code point is the scalar value encoded by that |
3014 | UTF-16 code unit sequence. |
3015 | |
3016 | - Otherwise, the computed code point is the UTF-16 code unit addressed |
3017 | by the index. (This last case catches unmatched surrogates as well as |
3018 | indices pointing into the middle of surrogate pairs.) |
3019 | |
3020 | @param indexUtf16 |
3021 | pointer to a UTF-16 based index into this string; must not be null. On |
3022 | entry, the index must be in the range from zero to the length of this |
3023 | string (in UTF-16 code units), inclusive. Upon successful return, the |
3024 | index will be updated to address the UTF-16 code unit that is the given |
3025 | incrementCodePoints away from the initial index. |
3026 | |
3027 | @param incrementCodePoints |
3028 | the number of code points to move the given *indexUtf16. If |
3029 | non-negative, moving is done after determining the code point at the |
3030 | index. If negative, moving is done before determining the code point |
3031 | at the (then updated) index. The value must be such that the resulting |
3032 | UTF-16 based index is in the range from zero to the length of this |
3033 | string (in UTF-16 code units), inclusive. |

3037 | that is represented within this string starting at the index computed as |
3038 | follows: If incrementCodePoints is non-negative, the index is the |
3039 | initial value of *indexUtf16; if incrementCodePoints is negative, the |
