org.springframework.aop .TargetSource

All known Subclasses:   org.springframework.aop.target .HotSwappableTargetSource,  org.springframework.aop.target .SingletonTargetSource,  org.springframework.aop.target .EmptyTargetSource,  org.springframework.aop.target .AbstractBeanFactoryBasedTargetSource,  org.springframework.aop.target .AbstractLazyCreationTargetSource,  org.springframework.aop.target.dynamic .AbstractRefreshableTargetSource,  org.springframework.jndi .JndiObjectTargetSource,
TargetSource
public interface TargetSource extends TargetClassAware(Code)
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.

Method Summary
Object getTarget()
     Return a target instance.
Class getTargetClass()
     Return the type of targets returned by this TargetSource .
boolean isStatic()
     Will all calls to TargetSource.getTarget() return the same object?
In that case, there will be no need to invoke TargetSource.releaseTarget(Object) , and the AOP framework can cache the return value of TargetSource.getTarget() .
void releaseTarget(Object target)
     Release the given target object obtained from the TargetSource.getTarget() method.

Method Detail
getTarget
Object getTarget() throws Exception(Code)
Return a target instance. Invoked immediately before the AOP framework calls the "target" of an AOP method invocation. the target object, which contains the joinpoint
throws:
  Exception - if the target object can't be resolved

getTargetClass
Class getTargetClass()(Code)
Return the type of targets returned by this TargetSource .
Can return null, although certain usages of a TargetSource might just work with a predetermined target class. the type of targets returned by this TargetSource

isStatic
boolean isStatic()(Code)
Will all calls to TargetSource.getTarget() return the same object?
In that case, there will be no need to invoke TargetSource.releaseTarget(Object) , and the AOP framework can cache the return value of TargetSource.getTarget() . true if the target is immutable
See Also:   TargetSource.getTarget

releaseTarget
void releaseTarget(Object target) throws Exception(Code)
Release the given target object obtained from the TargetSource.getTarget() method.
Parameters:
  target - object obtained from a call to TargetSource.getTarget()
throws:
  Exception - if the object can't be released
