| /** |
| * UnicodeString is a string class that stores Unicode characters directly and provides |
| * similar functionality as the Java String and StringBuffer classes. |
| * It is a concrete implementation of the abstract class Replaceable (for transliteration). |
| * |
| * The UnicodeString class is not suitable for subclassing. |
| * |
| * <p>For an overview of Unicode strings in C and C++ see the |
| * <a href="http://oss.software.ibm.com/icu/userguide/strings.html">User Guide Strings chapter</a>.</p> |
| * |
| * <p>In ICU, a Unicode string consists of 16-bit Unicode <em>code units</em>. |
| * A Unicode character may be stored with either |
| * one code unit — which is the most common case — or with a matched pair of |
| * special code units ("surrogates"). |
| * The data type for code units is UChar.<br> |
| * For single-character handling, a Unicode character code <em>point</em> is a value |
| * in the range 0..0x10ffff. ICU uses the UChar32 type for code points.</p> |
| * |
| * <p>Indexes and offsets into and lengths of strings always count code units, not code points. |
| * This is the same as with multi-byte char* strings in traditional string handling. |
| * Operations on partial strings typically do not test for code point boundaries. |
| * If necessary, the user needs to take care of such boundaries by testing for the code unit |
| * values or by using functions like |
| * UnicodeString::getChar32Start() and UnicodeString::getChar32Limit() |
| * (or, in C, the equivalent macros U16_SET_CP_START() and U16_SET_CP_LIMIT(), see utf.h).</p> |
| * |
| * UnicodeString methods are more lenient with regard to input parameter values |
| * than other ICU APIs. In particular: |
| * - If indexes are out of bounds for a UnicodeString object |
| * (<0 or >length()) then they are "pinned" to the nearest boundary. |
| * - If primitive string pointer values (e.g., const UChar * or char *) |
| * for input strings are NULL, then those input string parameters are treated |
| * as if they pointed to an empty string. |
| * However, this is <em>not</em> the case for char * parameters for charset names |
| * or other IDs. |
| * - Most UnicodeString methods do not take a UErrorCode parameter because |
| * there are usually very few opportunities for failure other than a shortage |
| * of memory, error codes in low-level C++ string methods would be inconvenient, |
| * and the error code as the last parameter (ICU convention) would prevent |
| * the use of default parameter values. |
| * Instead, such methods set the UnicodeString into a "bogus" state |
| * (see isBogus()) if an error occurs. |
| * |
| * In string comparisons, two UnicodeString objects that are both "bogus" |
| * compare equal (to be transitive and prevent endless loops in sorting), |
| * and a "bogus" string compares less than any non-"bogus" one. |
| * |
| * Const UnicodeString methods are thread-safe. Multiple threads can use |
| * const methods on the same UnicodeString object simultaneously, |
| * but non-const methods must not be called concurrently (in multiple threads) |
| * with any other (const or non-const) methods. |
| * |
| * Similarly, const UnicodeString & parameters are thread-safe. |
| * One object may be passed in as such a parameter concurrently in multiple threads. |
| * This includes the const UnicodeString & parameters for |
| * copy construction, assignment, and cloning. |
| * |
| * <p>UnicodeString uses several storage methods. |
| * String contents can be stored inside the UnicodeString object itself, |
| * in an allocated and shared buffer, or in an outside buffer that is "aliased". |
| * Most of this is done transparently, but careful aliasing in particular provides |
| * significant performance improvements. |
| * Also, the internal buffer is accessible via special functions. |
| * For details see the |
| * <a href="http://oss.software.ibm.com/icu/userguide/strings.html">User Guide Strings chapter</a>.</p> |
