Method Summary

Advice	getAdvice() Lazily instantiate advice if necessary.
MetadataAwareAspectInstanceFactory	getAspectInstanceFactory()
AspectMetadata	getAspectMetadata() Return the AspectJ AspectMetadata for this advisor.
String	getAspectName() The name of the aspect (bean) in which the advice was declared.
int	getDeclarationOrder() The declaration order of the advice member within the aspect.
AspectJExpressionPointcut	getDeclaredPointcut()
int	getOrder() Return the order value of this object, with a higher value meaning greater in terms of sorting.
Pointcut	getPointcut() The pointcut for Spring AOP to use.
boolean	isAdviceInstantiated() Return whether this advisor has already instantiated its advice.
boolean	isAfterAdvice() Return whether this is an after advice.
boolean	isBeforeAdvice() Return whether this is a before advice.
boolean	isLazy() Return whether this advisor is lazily initializing its underlying advice.
boolean	isPerInstance() This is only of interest for Spring AOP: AspectJ instantiation semantics are much richer.

Method Detail

getPointcut

public Pointcut getPointcut()

The pointcut for Spring AOP to use. Actual behaviour of the pointcut will change depending on the state of the advice.

Specified by:

getPointcut in interface PointcutAdvisor

isPerInstance

public boolean isPerInstance()

This is only of interest for Spring AOP: AspectJ instantiation semantics are much richer. In AspectJ terminology, all a return of true means here is that the aspect is not a SINGLETON.

Specified by:

isPerInstance in interface Advisor

getAspectMetadata

public AspectMetadata getAspectMetadata()

Return the AspectJ AspectMetadata for this advisor.

getAdvice

public Advice getAdvice()

Lazily instantiate advice if necessary.

Specified by:

getAdvice in interface Advisor

Returns:

the advice that should apply if the pointcut matches

See Also:

MethodInterceptor, BeforeAdvice, ThrowsAdvice, AfterReturningAdvice

isLazy

public boolean isLazy()

Description copied from interface: InstantiationModelAwarePointcutAdvisor

Return whether this advisor is lazily initializing its underlying advice.

Specified by:

isLazy in interface InstantiationModelAwarePointcutAdvisor

isAdviceInstantiated

public boolean isAdviceInstantiated()

Description copied from interface: InstantiationModelAwarePointcutAdvisor

Return whether this advisor has already instantiated its advice.

Specified by:

isAdviceInstantiated in interface InstantiationModelAwarePointcutAdvisor

getAspectInstanceFactory

public MetadataAwareAspectInstanceFactory getAspectInstanceFactory()

getDeclaredPointcut

public AspectJExpressionPointcut getDeclaredPointcut()

getOrder

public int getOrder()

Description copied from interface: Ordered

Return the order value of this object, with a higher value meaning greater in terms of sorting.

Normally starting with 0 or 1, with Ordered.LOWEST_PRECEDENCE indicating greatest. Same order values will result in arbitrary positions for the affected objects.

Higher value can be interpreted as lower priority, consequently the first object has highest priority (somewhat analogous to Servlet "load-on-startup" values).

Note that order values below 0 are reserved for framework purposes. Application-specified values should always be 0 or greater, with only framework components (internal or third-party) supposed to use lower values.

Specified by:

getOrder in interface Ordered

Returns:

the order value

See Also:

Ordered.LOWEST_PRECEDENCE

getAspectName

public String getAspectName()

Description copied from interface: AspectJPrecedenceInformation

The name of the aspect (bean) in which the advice was declared.

Specified by:

getAspectName in interface AspectJPrecedenceInformation

getDeclarationOrder

public int getDeclarationOrder()

Description copied from interface: AspectJPrecedenceInformation

The declaration order of the advice member within the aspect.

Specified by:

getDeclarationOrder in interface AspectJPrecedenceInformation

isBeforeAdvice

public boolean isBeforeAdvice()

Description copied from interface: AspectJPrecedenceInformation

Return whether this is a before advice.

Specified by:

isBeforeAdvice in interface AspectJPrecedenceInformation

isAfterAdvice

public boolean isAfterAdvice()

Description copied from interface: AspectJPrecedenceInformation

Return whether this is an after advice.

Specified by:

isAfterAdvice in interface AspectJPrecedenceInformation

toString

public String toString()

Overrides:

toString in class Object
