| Class containing static methods used to obtain information about the current AOP invocation.
The currentProxy() method is usable if the AOP framework is configured to
expose the current proxy (not the default). It returns the AOP proxy in use. Target objects
or advice can use this to make advised calls, in the same way as getEJBObject()
can be used in EJBs. They can also use it to find advice configuration.
Spring's AOP framework does not expose proxies by default, as there is a performance cost
in doing so.
The functionality in this class might be used by a target object that needed access
to resources on the invocation. However, this approach should not be used when there is
a reasonable alternative, as it makes application code dependent on usage under AOP and
the Spring AOP framework in particular.
