wrapObject

public static Object wrapObject(ClassLoader cl,
                                Object object,
                                InterfaceMonitor monitor,
                                Class<?>... interfacesToObserve)
                         throws IllegalArgumentException

returns an object that - apart from implementing the given interfaces - monitors each call to the object through the interfaces. The given object must implement all interfaces that are to be observed. The return value can then savely be casted to one of the given interfaces.

Returns:

a proxy object that monitors all calls to the given interface through the given monitor. The returned proxy can savely be casted to any of the given interfaces to be observed.

Throws:

IllegalArgumentException
