+/**
+ * A CharSequence is a readable sequence of char
values. This
+ * interface provides uniform, read-only access to many different kinds of
+ * char
sequences.
+ * A char
value represents a character in the Basic
+ * Multilingual Plane (BMP) or a surrogate. Refer to Unicode Character Representation for details.
+ *
+ *
This interface does not refine the general contracts of the {@link + * java.lang.Object#equals(java.lang.Object) equals} and {@link + * java.lang.Object#hashCode() hashCode} methods. The result of comparing two + * objects that implement CharSequence is therefore, in general, + * undefined. Each object may be implemented by a different class, and there + * is no guarantee that each class will be capable of testing its instances + * for equality with those of the other. It is therefore inappropriate to use + * arbitrary CharSequence instances as elements in a set or as keys in + * a map.
