| /** |
| * UnicodeString is a concrete implementation of the abstract class Replaceable. |
| * It is a string class that stores Unicode characters directly and provides |
| * similar functionality as the Java string class. |
| * |
| * UnicodeString uses four storage models: |
| * <ol> |
| * <li>Short strings are normally stored inside the UnicodeString object itself. |
| * The object has fields for the "bookkeeping" and a small UChar array. |
| * When the object is copied, then the internal characters are copied |
| * into the destination object.</li> |
| * <li>Longer strings are normally stored in allocated memory. |
| * The allocated UChar array is preceeded by a reference counter. |
| * When the string object is copied, then the allocated buffer is shared by |
| * incrementing the reference counter.</li> |
| * <li>A UnicodeString can be constructed or setTo() such that it aliases a read-only |
| * buffer instead of copying the characters. In this case, the string object |
| * uses this aliased buffer for as long as it is not modified, and it will never |
| * attempt to modify or release the buffer. This has copy-on-write semantics: |
| * When the string object is modified, then the buffer contents is first copied |
| * into writeable memory (inside the object for short strings, or allocated |
| * buffer for longer strings). When a UnicodeString with a read-only alias |
| * is assigned to another UnicodeString, then both string objects will |
| * share the same read-only alias.</li> |
| * <li>A UnicodeString can be constructed or setTo() such that it aliases a writeable |
| * buffer instead of copying the characters. The difference from the above is that |
| * the string object will write through to this aliased buffer for write |
| * operations. Only when the capacity of the buffer is not sufficient is |
| * a new buffer allocated and the contents copied. |
| * An efficient way to get the string contents into the original buffer is |
| * to use the extract(..., UChar *dst, ...) function: It will only copy the |
| * string contents if the dst buffer is different from the buffer of the string |
| * object itself. If a string grows and shrinks during a sequence of operations, |
| * then it will not use the same buffer any more, but may fit into it again. |
| * When a UnicodeString with a writeable alias is assigned to another UnicodeString, |
| * then the contents is always copied. The destination string will not alias |
| * to the buffer that the source string aliases.</li> |
| * </ol> |
