setProxyImplementation

public static boolean setProxyImplementation(java.lang.Object proxy,
                                             java.lang.Object impl)
                                      throws java.lang.IllegalArgumentException

Hot-swap implementation for a proxy object created by a proxy component. Components.proxy() and Component.proxy() methods expose a dynamic proxy instance and hide the real component instance. This method does hot-swapping, which changes the underlying real component instance to another object.

Parameters:

proxy - the proxied component instance.

impl - the object to change the underlying real instance to.

Returns:

true if the proxy is really created by the proxy() methods, false otherwise.

Throws:

java.lang.IllegalArgumentException - if the object does not implement all the interfaces the proxy implements.
