Class HotSwappableTargetSource

java.lang.Object
  org.springframework.aop.target.HotSwappableTargetSource

All Implemented Interfaces:: Serializable, TargetClassAware, TargetSource

public class HotSwappableTargetSource
extends Object
implements TargetSource, Serializable
extends Object
implements TargetSource, Serializable

TargetSource implementation that caches a local target object, but allows the target to be swapped while the application is running.

If configuring an object of this class in a Spring IoC container, use constructor injection.

This TargetSource is serializable if the target is at the time of serialization.
