| -/**
|
| - * <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.
