/**
* This interface defines an invocation handler. Suppose you are using
* reflection, and found a method that requires that its parameter
* be an object of a given interface. You want to call this method,
* but have no idea what classes implement that interface. So, you can
* create a {@link Proxy} instance, a convenient way to dynamically
* generate a class that meets all the necessary properties of that
* interface. But in order for the proxy instance to do any good, it
* needs to know what to do when interface methods are invoked! So,
* this interface is basically a cool wrapper that provides runtime
* code generation needed by proxy instances.<p>
*
* While this interface was designed for use by Proxy, it will also
* work on any object in general.<p>
*
* Hints for implementing this class:<br>
* <ul>
* <li>Don't forget that Object.equals, Object.hashCode, and
* Object.toString will call this handler. In particular,
* a naive call to proxy.equals, proxy.hashCode, or proxy.toString
* will put you in an infinite loop. And remember that string
* concatenation also invokes toString.</li>
* <li>Obey the contract of the Method object you are handling, or
* the proxy instance will be forced to throw a
* {@link NullPointerException}, {@link ClassCastException},
* or {@link UndeclaredThrowableException}.</li>
* <li>Be prepared to wrap/unwrap primitives as necessary.</li>
* <li>The Method object may be owned by a different interface than
* what was actually used as the qualifying type of the method
* invocation in the Java source code. This means that it might
* not always be safe to throw an exception listed as belonging
* to the method's throws clause.</li>
* </ul>
*
* <p><small>For a fun time, create an InvocationHandler that handles the
* methods of a proxy instance of the InvocationHandler interface!</small>

/**
* When a method is invoked on a proxy instance, it is wrapped and
* this method is called instead, so that you may decide at runtime
* how the original method should behave.
*
* @param proxy the instance that the wrapped method should be
* invoked on. When this method is called by a Proxy object,
* `proxy' will be an instance of {@link Proxy}, and oddly enough,
* <code>Proxy.getInvocationHandler(proxy)</code> will return
* <code>this</code>!
* @param method the reflected method to invoke on the proxy.
* When this method is called by a Proxy object, 'method'
* will be the reflection object owned by the declaring
* class or interface, which may be a supertype of the
* interfaces the proxy directly implements.
* @param args the arguments passed to the original method, or
* <code>null</code> if the method takes no arguments.
* (But also be prepared to handle a 0-length array).
* Arguments of primitive type, such as <code>boolean</code>
* or <code>int</code>, are wrapped in the appropriate
* class such as {@link Boolean} or {@link Integer}.
* @return whatever is necessary to return from the wrapped method.
* If the wrapped method is <code>void</code>, the proxy
* instance will ignore it. If the wrapped method returns
* a primitive, this must be the correct wrapper type whose value
* is exactly assignable to the appropriate type (no widening
* will be performed); a null object in this case causes a
* {@link NullPointerException}. In all remaining cases, if
* the returned object is not assignment compatible to the
* declared type of the original method, the proxy instance
* will generate a {@link ClassCastException}.
* @throws Throwable this interface is listed as throwing anything,
* but the implementation should only throw unchecked
* exceptions and exceptions listed in the throws clause of
* all methods being overridden by the proxy instance. If
* something is thrown that is not compatible with the throws
* clause of all overridden methods, the proxy instance will
* wrap the exception in an UndeclaredThrowableException.
* Note that an exception listed in the throws clause of the

* interfaces also implemented by the proxy object.
