Interface to be implemented by factories that are able to create AOP proxies based on AdvisedSupport configuration objects. 
Proxies should observe the following contract:

    

  • They should implement all interfaces that the configuration
indicates should be proxied.

  • They should implement the Advised interface. 
  • They should implement the equals method to compare proxied
interfaces, advice, and target.

  • They should be serializable if all advisors and target
are serializable.

  • They should be thread-safe if advisors and target
are thread-safe.



Proxies may or may not allow advice changes to be made. If they do not permit advice changes (for example, because the configuration was frozen) a proxy should throw an AopConfigException on an attempted advice change.
