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

Returns:

whether this advice is associated with a particular target instance

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:

org.aopalliance.intercept.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

instantiateAdvice

private Advice instantiateAdvice(AspectJExpressionPointcut pcut)

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, with Integer.MAX_VALUE indicating the greatest value. Same order values will result in arbitrary positions for the affected objects.

Higher values can be interpreted as lower priority. As a consequence, the object with the lowest value has highest priority (somewhat analogous to Servlet "load-on-startup" values).

Specified by:

getOrder in interface Ordered

Returns:

the order value

getAspectName

public java.lang.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

determineAdviceType

private void determineAdviceType()

Duplicates some logic from getAdvice, but importantly does not force creation of the advice.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
