Advised

All Superinterfaces:

TargetClassAware

All Known Implementing Classes:

AdvisedSupport, AspectJProxyFactory, ProxyCreatorSupport, ProxyFactory, ProxyFactoryBean
```
public interface Advised
extends TargetClassAware
```
Interface to be implemented by classes that hold the configuration of a factory of AOP proxies. This configuration includes the Interceptors and other advice, Advisors, and the proxied interfaces.
Any AOP proxy obtained from Spring can be cast to this interface to allow manipulation of its AOP advice.

`void`	`addAdvice(int pos, Advice advice)` Add the given AOP Alliance Advice at the specified position in the advice chain.
`void`	`addAdvisor(Advisor advisor)` Add an advisor at the end of the advisor chain.
`void`	`addAdvisor(int pos, Advisor advisor)` Add an Advisor at the specified position in the chain.
`Advisor[]`	`getAdvisors()` Return the advisors applying to this proxy.
`java.lang.Class<?>[]`	`getProxiedInterfaces()` Return the interfaces proxied by the AOP proxy.
`TargetSource`	`getTargetSource()` Return the `TargetSource` used by this `Advised` object.
`int`	`indexOf(Advice advice)` Return the index (from 0) of the given AOP Alliance Advice, or -1 if no such advice is an advice for this proxy.
`int`	`indexOf(Advisor advisor)` Return the index (from 0) of the given advisor, or -1 if no such advisor applies to this proxy.
`boolean`	`isExposeProxy()` Return whether the factory should expose the proxy as a `ThreadLocal`.
`boolean`	`isFrozen()` Return whether the Advised configuration is frozen, in which case no advice changes can be made.
`boolean`	`isInterfaceProxied(java.lang.Class<?> intf)` Determine whether the given interface is proxied.
`boolean`	`isPreFiltered()` Return whether this proxy configuration is pre-filtered so that it only contains applicable advisors (matching this proxy's target class).
`boolean`	`isProxyTargetClass()` Are we proxying the full target class instead of specified interfaces?

getTargetClass

- Method Detail
  - isFrozen
```
boolean isFrozen()
```
    Return whether the Advised configuration is frozen, in which case no advice changes can be made.
  - isProxyTargetClass
```
boolean isProxyTargetClass()
```
    Are we proxying the full target class instead of specified interfaces?
  - getProxiedInterfaces
```
java.lang.Class<?>[] getProxiedInterfaces()
```
    Return the interfaces proxied by the AOP proxy.
    Will not include the target class, which may also be proxied.
  - isInterfaceProxied
```
boolean isInterfaceProxied(java.lang.Class<?> intf)
```
    Determine whether the given interface is proxied.
    
    Parameters:
    
    intf - the interface to check
  - setTargetSource
```
void setTargetSource(TargetSource targetSource)
```
    Change the TargetSource used by this Advised object.
    Only works if the configuration isn't frozen.
    
    Parameters:
    
    targetSource - new TargetSource to use
  - getTargetSource
```
TargetSource getTargetSource()
```
    Return the TargetSource used by this Advised object.
  - setExposeProxy
```
void setExposeProxy(boolean exposeProxy)
```
    Set whether the proxy should be exposed by the AOP framework as a ThreadLocal for retrieval via the AopContext class.
    It can be necessary to expose the proxy if an advised object needs to invoke a method on itself with advice applied. Otherwise, if an advised object invokes a method on this, no advice will be applied.
    Default is false, for optimal performance.
  - isExposeProxy
```
boolean isExposeProxy()
```
    Return whether the factory should expose the proxy as a ThreadLocal.
    It can be necessary to expose the proxy if an advised object needs to invoke a method on itself with advice applied. Otherwise, if an advised object invokes a method on this, no advice will be applied.
    Getting the proxy is analogous to an EJB calling getEJBObject().

    AopContext
  - setPreFiltered
```
void setPreFiltered(boolean preFiltered)
```
    Set whether this proxy configuration is pre-filtered so that it only contains applicable advisors (matching this proxy's target class).
    Default is "false". Set this to "true" if the advisors have been pre-filtered already, meaning that the ClassFilter check can be skipped when building the actual advisor chain for proxy invocations.

    ClassFilter
  - isPreFiltered
```
boolean isPreFiltered()
```

```
    Return the advisors applying to this proxy.
    
    Returns:
    
    a list of Advisors applying to this proxy (never null)

```
void addAdvisor(Advisor advisor)
         throws AopConfigException

    The Advisor may be an IntroductionAdvisor, in which new interfaces will be available when a proxy is next obtained from the relevant factory.
    
    Parameters:
    
    advisor - the advisor to add to the end of the chain
    
    Throws:
    
    AopConfigException - in case of invalid advice

    true if the advisor was removed; false if the advisor was not found and hence could not be removed
  - removeAdvisor
```
void removeAdvisor(int index)
            throws AopConfigException
```
    Remove the advisor at the given index.
    
    Parameters:
    
    index - index of advisor to remove
    
    Throws:
    
    AopConfigException - if the index is invalid
  - indexOf
```
int indexOf(Advisor advisor)
```
    Return the index (from 0) of the given advisor, or -1 if no such advisor applies to this proxy.
    The return value of this method can be used to index into the advisors array.
    
    Parameters:
    
    advisor - the advisor to search for
    
    Returns:
    
    index from 0 of this advisor, or -1 if there's no such advisor
  - replaceAdvisor
```
boolean replaceAdvisor(Advisor a,
                       Advisor b)
                throws AopConfigException
```
    Replace the given advisor.
    Note: If the advisor is an IntroductionAdvisor and the replacement is not or implements different interfaces, the proxy will need to be re-obtained or the old interfaces won't be supported and the new interface won't be implemented.
    
    Parameters:
    
    a - the advisor to replace
    
    b - the advisor to replace it with
    
    Returns:
    
    whether it was replaced. If the advisor wasn't found in the list of advisors, this method returns false and does nothing.
    
    Throws:
    
    AopConfigException - in case of invalid advice
  - addAdvice
```
void addAdvice(Advice advice)
        throws AopConfigException
```
    Add the given AOP Alliance advice to the tail of the advice (interceptor) chain.
    This will be wrapped in a DefaultPointcutAdvisor with a pointcut that always applies, and returned from the getAdvisors() method in this wrapped form.
    Note that the given advice will apply to all invocations on the proxy, even to the toString() method! Use appropriate advice implementations or specify appropriate pointcuts to apply to a narrower set of methods.
    
    Parameters:
    
    advice - advice to add to the tail of the chain
    
    Throws:
    
    AopConfigException - in case of invalid advice
