apache-commons-proxy - Apache Commons Proxy Component
- Description:
The Proxy design pattern (GoF ) allows you to provide "a
surrogate or placeholder for another object to control
access to it". Proxies can be used in many ways. Some of
which are:
* Deferred Initialization - the proxy acts as a "stand-in"
for the actual implementation allowing it to be
instantiated only when absolutely necessary.
* Security - the proxy object can verify that the user
actually has the permission to execute the method (a la
EJB).
* Logging - the proxy can log evey method invocation,
providing valuable debugging information.
* Performance Monitoring - the proxy can log each method
invocation to a performance monitor allowing system
administrators to see what parts of the system are
potentially bogged down.
Commons Proxy supports dynamic proxy generation using proxy
factories, object providers, invokers, and interceptors.
