Method Detail

getTargetClass

public static Class getTargetClass(Object proxy)

Return the target class of the given bean instance.

Returns the target class for an AOP proxy and the plain bean class else.

Parameters:

proxy - the instance to check (might be an AOP proxy)

Returns:

the target class

Advised.getTargetSource(), TargetSource.getTargetClass()

completeProxiedInterfaces

public static Class[] completeProxiedInterfaces(AdvisedSupport advised)

Get complete set of interfaces to proxy. This will always add the Advised interface unless the AdvisedSupport's "opaque" flag is true.

Returns:

the complete set of interfaces to proxy

proxiedUserInterfaces

public static Class[] proxiedUserInterfaces(Object proxy)

Extract the user-specified interfaces that the given proxy implements, i.e. all non-Advised interfaces that the proxy implements.

Parameters:

proxy - the proxy to analyze (usually a JDK dynamic proxy)

Returns:

all user-specified interfaces that the proxy implements, in the original order (never null or empty)

equalsInProxy

public static boolean equalsInProxy(AdvisedSupport a,
                                    AdvisedSupport b)

Check equality of the proxies behind the given AdvisedSupport objects. Not the same as equality of the AdvisedSupport objects: rather, equality of interfaces, advisors and target sources.

equalsProxiedInterfaces

public static boolean equalsProxiedInterfaces(AdvisedSupport a,
                                              AdvisedSupport b)

Check equality of the proxied interfaces behind the given AdvisedSupport objects.

equalsAdvisors

public static boolean equalsAdvisors(AdvisedSupport a,
                                     AdvisedSupport b)

Check equality of the advisors behind the given AdvisedSupport objects.
