private boolean	shouldInvokeOnReturnValueOf(Method method, Object returnValue)	Following AspectJ semantics, if a returning clause was specified, then the advice is only invoked if the returned value is an instance of the given returning type and generic type parameters, if any, match the assignment rules.

isBeforeAdvice

public boolean isBeforeAdvice()

从接口复制的说明: AspectJPrecedenceInformation

Return whether this is a before advice.

指定者:

isBeforeAdvice 在接口中 AspectJPrecedenceInformation

isAfterAdvice

public boolean isAfterAdvice()

从接口复制的说明: AspectJPrecedenceInformation

Return whether this is an after advice.

指定者:

isAfterAdvice 在接口中 AspectJPrecedenceInformation

setReturningName

public void setReturningName(String name)

覆盖:

setReturningName 在类中 AbstractAspectJAdvice

afterReturning

public void afterReturning(Object returnValue,
 MethodInvocation invocation)
                    throws Throwable

从接口复制的说明: AfterReturningAdvice

Callback after a given method successfully returned.

指定者:

afterReturning 在接口中 AfterReturningAdvice

参数:

returnValue - the value returned by the method, if any

invocation - the method invocation join-point

抛出:

Throwable - if this object wishes to abort the call. Any exception thrown will be returned to the caller if it's allowed by the method signature. Otherwise the exception will be wrapped as a runtime exception.

shouldInvokeOnReturnValueOf

private boolean shouldInvokeOnReturnValueOf(Method method,
 @Nullable
 Object returnValue)

Following AspectJ semantics, if a returning clause was specified, then the advice is only invoked if the returned value is an instance of the given returning type and generic type parameters, if any, match the assignment rules. If the returning type is Object, the advice is *always* invoked.

参数:

returnValue - the return value of the target method

返回:

whether to invoke the advice method for the given return value

matchesReturnValue

private boolean matchesReturnValue(Class<?> type,
 Method method,
 @Nullable
 Object returnValue)

Following AspectJ semantics, if a return value is null (or return type is void), then the return type of target method should be used to determine whether advice is invoked or not. Also, even if the return type is void, if the type of argument declared in the advice method is Object, then the advice must still get invoked.

参数:

type - the type of argument declared in advice method

method - the advice method

returnValue - the return value of the target method

返回:

whether to invoke the advice method for the given return value and type
