29 * {@code InvocationHandler} is the interface implemented by
30 * the <i>invocation handler</i> of a proxy instance.
32 * <p>Each proxy instance has an associated invocation handler.
33 * When a method is invoked on a proxy instance, the method
34 * invocation is encoded and dispatched to the {@code invoke}
35 * method of its invocation handler.
41 public interface InvocationHandler {
44 * Processes a method invocation on a proxy instance and returns
45 * the result. This method will be invoked on an invocation handler
46 * when a method is invoked on a proxy instance that it is
49 * @param proxy the proxy instance that the method was invoked on
51 * @param method the {@code Method} instance corresponding to
52 * the interface method invoked on the proxy instance. The declaring
53 * class of the {@code Method} object will be the interface that
54 * the method was declared in, which may be a superinterface of the
55 * proxy interface that the proxy class inherits the method through.
57 * @param args an array of objects containing the values of the
58 * arguments passed in the method invocation on the proxy instance,
59 * or {@code null} if interface method takes no arguments.
60 * Arguments of primitive types are wrapped in instances of the
61 * appropriate primitive wrapper class, such as
62 * {@code java.lang.Integer} or {@code java.lang.Boolean}.
64 * @return the value to return from the method invocation on the
65 * proxy instance. If the declared return type of the interface
66 * method is a primitive type, then the value returned by
67 * this method must be an instance of the corresponding primitive
68 * wrapper class; otherwise, it must be a type assignable to the
69 * declared return type. If the value returned by this method is
70 * {@code null} and the interface method's return type is
71 * primitive, then a {@code NullPointerException} will be
72 * thrown by the method invocation on the proxy instance. If the
73 * value returned by this method is otherwise not compatible with
74 * the interface method's declared return type as described above,
75 * a {@code ClassCastException} will be thrown by the method
76 * invocation on the proxy instance.
78 * @throws Throwable the exception to throw from the method
79 * invocation on the proxy instance. The exception's type must be
80 * assignable either to any of the exception types declared in the
81 * {@code throws} clause of the interface method or to the
82 * unchecked exception types {@code java.lang.RuntimeException}
83 * or {@code java.lang.Error}. If a checked exception is
84 * thrown by this method that is not assignable to any of the
85 * exception types declared in the {@code throws} clause of
86 * the interface method, then an
87 * {@link UndeclaredThrowableException} containing the
88 * exception that was thrown by this method will be thrown by the
89 * method invocation on the proxy instance.
