public AopProxyUtils()

Method Detail

getTargetClass

public static Class getTargetClass(Object candidate)

Deprecated. as of Spring 2.0.3, in favor of AopUtils.getTargetClass

Determine the target class of the given bean instance, which might be an AOP proxy.

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

Parameters:

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

Returns:

the target class (or the plain class of the given object as fallback)

AopUtils.getTargetClass(Object)

completeProxiedInterfaces

public static Class[] completeProxiedInterfaces(AdvisedSupport advised)

Determine the complete set of interfaces to proxy for the given AOP configuration.

This will always add the Advised interface unless the AdvisedSupport's "opaque" flag is on. Always adds the SpringProxy marker interface.

Returns:

the complete set of interfaces to proxy

See Also:

Advised, SpringProxy

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)

Advised

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.
