getInvocationHandler

public static java.lang.reflect.InvocationHandler getInvocationHandler(java.lang.Object proxy)

Get the invocation handler of a proxy.

Parameters:

proxy -

Returns:

The handler

newProxyInstance

public static java.lang.Object newProxyInstance(java.lang.ClassLoader loader,
                                                java.lang.Class<?>[] ifaces,
                                                java.lang.reflect.InvocationHandler handler)

Generate a proxy for an existing class.

Parameters:

loader - The class loader.

ifaces - The interfaces (may contain one clazz).

handler - The invocation handler.

Returns:

The new proxy extending the clazz and implementing all interfaces.

newProxyInstance

public static java.lang.Object newProxyInstance(java.lang.ClassLoader loader,
                                                java.lang.Class<?> clazz,

                                                java.lang.reflect.InvocationHandler handler)

Generate a proxy for an existing class.

Parameters:

loader - The class loader.

clazz - The clazz.

ifaces - The interfaces.

handler - The invocation handler.

Returns:

The new proxy extending the clazz and implementing all interfaces.

genrateInvocationCode

protected static MethodNode genrateInvocationCode(MethodNode m,
                                                  java.lang.String classname,
                                                  java.lang.Class<?> iface,
                                                  java.lang.ClassLoader loader)
                                           throws java.lang.Exception

Generate the code for delegating the call to the invocation handler.

Parameters:

m - The methodnode.

classname - The class name.

iface - The interface (null means the class is owner of the method)

Returns:

The new method node (or null).

Throws:

java.lang.Exception

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Main for testing.
