Package net.ggtools.smartproxy

This package provides classes to wrap an underlying object into a proxy in order to change the behaviour of some methods (eg: transparently adding a cache) while leaving the other's untouched by forwarding the calls to the underlying object.

Interface Summary

ProxifiedObject	This is the base interface that the implementor objects need to implements.
ProxyClassGenerator	Interface for proxy class generators.

Class Summary

ProxyFactory	A factory to create proxified objects.

Package net.ggtools.smartproxy Description

This package provides classes to wrap an underlying object into a proxy in order to change the behaviour of some methods (eg: transparently adding a cache) while leaving the other's untouched by forwarding the calls to the underlying object. The package was designed to be efficient and hassle free. Efficient because the generated proxies should have performances roughly equivalent to hand coded ones. Hassle free because it should let the programmer concentrate on what the proxy should do (the changed methods) rather than on what it should not (the delegated methods). To achieve this, the proxification process is entirely done at runtime by creating the need proxy classes on the fly.

The following terminology is used in the package's documentation:

base interface

the interface the generated proxy class should implement,

implementor class

an abstract class implementing the methods to be altered by the proxy, this class must implement the ProxifiedObject interface,

underlying interface

the interface of the underlying objects.

Depending on the actual proxy generator these three interfaces/classes may or may not be necessary.

This product includes software developed by the Apache Software Foundation.
