Class AopProxy

java.lang.Object
  |
  +--com.interface21.aop.framework.AopProxy

All Implemented Interfaces:

java.lang.reflect.InvocationHandler

public class AopProxy

extends java.lang.Object

implements java.lang.reflect.InvocationHandler

InvocationHandler implementation for the Spring AOP framework, based on Java 1.3+ dynamic proxies. Objects of this type should be obtained through proxy factories, configured by a ProxyConfig implementation. This class is internal to the Spring framework and need not be used directly by client code.
Proxies created using this class can be threadsafe if the underlying (target) class is threadsafe.

Constructor Detail

AopProxy

public AopProxy(ProxyConfig config)
         throws AopConfigException

Throws:

AopConfigException - if the config is invalid. We try to throw an informative exception in this case, rather than let a mysterious failure happen later.

Method Detail

getProxy

public static java.lang.Object getProxy(AopProxy aop)

Returns:

a new Proxy object for the given object proxying the given interface

getProxy

public static java.lang.Object getProxy(java.lang.ClassLoader cl,
                                        AopProxy aop)

Returns:

a new Proxy object for the given object proxying the given interface

invoke

public final java.lang.Object invoke(java.lang.Object proxy,
                                     java.lang.reflect.Method method,
                                     java.lang.Object[] args)
                              throws java.lang.Throwable

Implementation of InvocationHandler.invoke. Callers will see exactly the exception thrown by the target, unless a hook method throws an exception.

Specified by:

invoke in interface java.lang.reflect.InvocationHandler

equals

public boolean equals(java.lang.Object other)

Equality means interceptors and interfaces are ==

Overrides:

equals in class java.lang.Object

Parameters:

other - may be a dynamic proxy wrapping an instance of this class
