1.33 - * A <tt>CharSequence</tt> is a readable sequence of <code>char</code> values. This
1.34 - * interface provides uniform, read-only access to many different kinds of
1.35 - * <code>char</code> sequences.
1.36 - * A <code>char</code> value represents a character in the <i>Basic
1.37 - * Multilingual Plane (BMP)</i> or a surrogate. Refer to <a
1.38 - * href="Character.html#unicode">Unicode Character Representation</a> for details.
1.39 - *
1.40 - * <p> This interface does not refine the general contracts of the {@link
1.41 - * java.lang.Object#equals(java.lang.Object) equals} and {@link
1.42 - * java.lang.Object#hashCode() hashCode} methods. The result of comparing two
1.43 - * objects that implement <tt>CharSequence</tt> is therefore, in general,
1.44 - * undefined. Each object may be implemented by a different class, and there
1.45 - * is no guarantee that each class will be capable of testing its instances
1.46 - * for equality with those of the other. It is therefore inappropriate to use
1.47 - * arbitrary <tt>CharSequence</tt> instances as elements in a set or as keys in
1.48 - * a map. </p>
