It is used by APIs that * change a piece of text while retaining metadata. Metadata is data * other than the Unicode characters returned by char32At(). One * example of metadata is style attributes; another is an edit * history, marking each character with an author and revision number. * * <p>An implicit aspect of the <code>Replaceable</code> API is that * during a replace operation, new characters take on the metadata of * the old characters. For example, if the string "the <b>bold</b> * font" has range (4, 8) replaced with "strong", then it becomes "the * <b>strong</b> font". * * <p><code>Replaceable</code> specifies ranges using a start * offset and a limit offset. The range of characters thus specified * includes the characters at offset start..limit-1. That is, the * start offset is inclusive, and the limit offset is exclusive. * * <p><code>Replaceable</code> also includes API to access characters * in the string: <code>length()</code>, <code>charAt()</code>, * <code>char32At()</code>, and <code>extractBetween()</code>. * * <p>For a subclass to support metadata, typical behavior of * <code>replace()</code> is the following: * <ul> * <li>Set the metadata of the new text to the metadata of the first * character replaced</li> * <li>If no characters are replaced, use the metadata of the * previous character</li> * <li>If there is no previous character (i.e. start == 0), use the * following character</li> * <li>If there is no following character (i.e. the replaceable was * empty), use default metadata.<br> * <li>If the code point U+FFFF is seen, it should be interpreted as * a special marker having no metadata<li> * </li> * </ul> * If this is not the behavior, the subclass should document any differences. * @author Alan Liu * @stable ICU 2.0 */ class U_COMMON_API Replaceable : public UObject { public: /** * Destructor. * @stable ICU 2.0 */ virtual ~Replaceable(); /** * Returns the number of 16-bit code units in the text. * @return number of 16-bit code units in text * @stable ICU 1.8 */ inline int32_t length() const; /** * Returns the 16-bit code unit at the given offset into the text. * @param offset an integer between 0 and <code>length()</code>-1 * inclusive * @return 16-bit code unit of text at given offset * @stable ICU 1.8 */ inline char16_t charAt(int32_t offset) const; /** * Returns the 32-bit code point at the given 16-bit offset into * the text.
