simpler.

+ * The client adapter makes life easier for client observer classes that
+ * only care about one or two of the client observer callbacks. They can
+ * either extend client adapter or create an anonymous class that extends
+ * it and overrides just the callbacks they care about.
+ *
+ * <p> Note that the client adapter defaults to always ratifying a call to
+ * {@link * #clientWillLogoff} by returning true.
