Interface TargetSource

All Known Implementing Classes:

AbstractPrototypeTargetSource, HotSwappableTargetSource, SingletonTargetSource

public interface TargetSource

A TargetSource is used to obtain the current "target" of an AOP invocation, which will be invoked via reflection if no around advice chooses to end the interceptor chain itself.
If a TargetSource is "static", it will always return the same target, allowing optimizations in the AOP framework. Dynamic target sources can support pooling, hot swapping etc.
Application developers don't usually need to work with TargetSources directly: this is an AOP framework interface.
