Java In A Nutshell, 5th Edition

CallbackHandler implementations may throw exceptions of this type from their handle( ) method if a Callback object passed to that method is of an unrecognized or unsupported type. Note that the offending Callback object must be passed to the constructor method.

public class UnsupportedCallbackException extends Exception { // Public Constructors public UnsupportedCallbackException (Callback callback ); public UnsupportedCallbackException (Callback callback , String msg ); // Public Instance Methods public Callback getCallback ( ); }
