-class UnicodeString;

-/**
- * <code>Replaceable</code> is an abstract base class representing a
- * string of characters that supports the replacement of a range of
- * itself with a new string of characters. 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.
