- すべての実装インタフェース:
- java.lang.reflect.InvocationHandler
- public final class DynamicProxy
- extends java.lang.Object
- implements java.lang.reflect.InvocationHandler
This makes a dynamic proxy for an object. The object can be represented
by one, some of all of it's interfaces.
Amongst other things, it's an anti hackinge measure. Suitable armed code
could have case an interface for a thing back to it's impl and used methods
and properties that were not it's authors intention. Reflection too allows
some powerful introspection things and some traversal even more things
including private member vars by a serialisation trick... hence the transient.
