41+ * <p>Interface for enabling iteration over sets of <int index, int value>,
42+ * where index is the sorted integer index in ascending order and value, its
43+ * associated integer value.</p>
44+ * <p>The result for each iteration is the consecutive range of
45+ * <int index, int value> with the same value. Result is represented by
46+ * <start, limit, value> where</p>
47+ * <ul>
48+ * <li> start is the starting integer of the result range
49+ * <li> limit is 1 after the maximum integer that follows start, such that
50+ * all integers between start and (limit - 1), inclusive, have the same
51+ * associated integer value.
52+ * <li> value is the integer value that all integers from start to (limit - 1)
53+ * share in common.
54+ * </ul>
55+ * <p>
56+ * Hence value(start) = value(start + 1) = .... = value(start + n) = .... =
57+ * value(limit - 1). However value(start -1) != value(start) and
58+ * value(limit) != value(start).
59+ * </p>
60+ * <p>Most implementations will be created by factory methods, such as the
61+ * character type iterator in UCharacter.getTypeIterator. See example below.
62+ * </p>
63+ * Example of use:<br>
64+ * <pre>
65+ * RangeValueIterator iterator = UCharacter.getTypeIterator();
66+ * RangeValueIterator.Element result = new RangeValueIterator.Element();
67+ * while (iterator.next(result)) {
68+ * System.out.println("Codepoint \\u" +
69+ * Integer.toHexString(result.start) +
70+ * " to codepoint \\u" +
71+ * Integer.toHexString(result.limit - 1) +
72+ * " has the character type " + result.value);
73+ * }
74+ * </pre>
