Class Overview

Utility methods for AOP proxy factories. Mainly for internal use within the AOP framework.

See AopUtils for a collection of generic AOP utility methods which do not depend on AOP framework internals.

Public Methods
static Class[] completeProxiedInterfaces(AdvisedSupport advised)
Determine the complete set of interfaces to proxy for the given AOP configuration.
static boolean equalsAdvisors(AdvisedSupport a, AdvisedSupport b)
Check equality of the advisors behind the given AdvisedSupport objects.
static boolean equalsInProxy(AdvisedSupport a, AdvisedSupport b)
Check equality of the proxies behind the given AdvisedSupport objects.
static boolean equalsProxiedInterfaces(AdvisedSupport a, AdvisedSupport b)
Check equality of the proxied interfaces behind the given AdvisedSupport objects.
static Class[] proxiedUserInterfaces(Object proxy)
Extract the user-specified interfaces that the given proxy implements, i.e.
static Class<?> ultimateTargetClass(Object candidate)
Determine the ultimate target class of the given bean instance, traversing not only a top-level proxy but any number of nested proxies as well - as long as possible without side effects, that is, just for singleton targets.

Public Methods

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

public static boolean equalsAdvisors (AdvisedSupport a, AdvisedSupport b)

Check equality of the advisors behind the given AdvisedSupport objects.

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.

public static boolean equalsProxiedInterfaces (AdvisedSupport a, AdvisedSupport b)

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

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)
See Also

public static Class<?> ultimateTargetClass (Object candidate)

Determine the ultimate target class of the given bean instance, traversing not only a top-level proxy but any number of nested proxies as well - as long as possible without side effects, that is, just for singleton targets.

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; never null)
