/**
 * This interface defines a protocol for bidirectional iteration over text.
 * The iterator iterates over a bounded sequence of characters.  Characters
 * are indexed with values beginning with the value returned by getBeginIndex() and
 * continuing through the value returned by getEndIndex()-1.
 * <p>
 * Iterators maintain a current character index, whose valid range is from
 * getBeginIndex() to getEndIndex(); the value getEndIndex() is included to allow
 * handling of zero-length text ranges and for historical reasons.
 * The current index can be retrieved by calling getIndex() and set directly
 * by calling setIndex(), first(), and last().
 * <p>
 * The methods previous() and next() are used for iteration. They return DONE if
 * they would move outside the range from getBeginIndex() to getEndIndex() -1,
 * signaling that the iterator has reached the end of the sequence. DONE is
 * also returned by other methods to indicate that the current index is
 * outside this range.
 *
 * <P>Examples:<P>
 *
 * Traverse the text from start to finish
 * <pre>{@code
 * public void traverseForward(CharacterIterator iter) {
 *     for(char c = iter.first(); c != CharacterIterator.DONE; c = iter.next()) {
 *         processChar(c);
 *     }
 * }
 * }</pre>
 *
 * Traverse the text backwards, from end to start
 * <pre>{@code
 * public void traverseBackward(CharacterIterator iter) {
 *     for(char c = iter.last(); c != CharacterIterator.DONE; c = iter.previous()) {
 *         processChar(c);
 *     }
 * }
 * }</pre>
 *
 * Traverse both forward and backward from a given position in the text.
 * Calls to notBoundary() in this example represents some
 * additional stopping criteria.
 * <pre>{@code
 * public void traverseOut(CharacterIterator iter, int pos) {
 *     for (char c = iter.setIndex(pos);
 *              c != CharacterIterator.DONE && notBoundary(c);
 *              c = iter.next()) {
 *     }
 *     int end = iter.getIndex();
 *     for (char c = iter.setIndex(pos);
 *             c != CharacterIterator.DONE && notBoundary(c);
 *             c = iter.previous()) {
 *     }
 *     int start = iter.getIndex();
 *     processSection(start, end);
 * }
 * }</pre>
