      extended by org.springframework.aop.aspectj.AspectJExpressionPointcut
All Implemented Interfaces:
Serializable, ClassFilter, IntroductionAwareMethodMatcher, MethodMatcher, Pointcut, ExpressionPointcut, Aware, BeanFactoryAware

public class AspectJExpressionPointcut
extends AbstractExpressionPointcut
implements ClassFilter, IntroductionAwareMethodMatcher, BeanFactoryAware

Spring Pointcut implementation that uses the AspectJ weaver to evaluate a pointcut expression.

The pointcut expression value is an AspectJ expression. This can reference other pointcuts and use composition and other operations.

Naturally, as this is to be processed by Spring AOP's proxy-based model, only method execution pointcuts are supported.

Since:
2.0

Constructor Detail

AspectJExpressionPointcut

public AspectJExpressionPointcut()
Create a new default AspectJExpressionPointcut.


AspectJExpressionPointcut

public AspectJExpressionPointcut(Class declarationScope,
                                 String[] paramNames,
                                 Class[] paramTypes)
Create a new AspectJExpressionPointcut with the given settings.

Parameters:
declarationScope - the declaration scope for the pointcut
paramNames - the parameter names for the pointcut
paramTypes - the parameter types for the pointcut
Method Detail

setPointcutDeclarationScope

public void setPointcutDeclarationScope(Class pointcutDeclarationScope)
Set the declaration scope for the pointcut.


setParameterNames

public void setParameterNames(String[] names)
Set the parameter names for the pointcut.


setParameterTypes

public void setParameterTypes(Class[] types)
Set the parameter types for the pointcut.


setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)
Description copied from interface: BeanFactoryAware
Callback that supplies the owning factory to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean.afterPropertiesSet() or a custom init-method.

Specified by:
setBeanFactory in interface BeanFactoryAware
Parameters:
beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.
See Also:
BeanInitializationException

getClassFilter

public ClassFilter getClassFilter()
Description copied from interface: Pointcut
Return the ClassFilter for this pointcut.

Specified by:
getClassFilter in interface Pointcut
Returns:
the ClassFilter (never null)

getMethodMatcher

public MethodMatcher getMethodMatcher()
Description copied from interface: Pointcut
Return the MethodMatcher for this pointcut.

Specified by:
getMethodMatcher in interface Pointcut
Returns:
the MethodMatcher (never null)

getPointcutExpression

public org.aspectj.weaver.tools.PointcutExpression getPointcutExpression()
Return the underlying AspectJ pointcut expression.


matches

public boolean matches(Class targetClass)
Description copied from interface: ClassFilter
Should the pointcut apply to the given interface or target class?

Specified by:
matches in interface ClassFilter
Parameters:
targetClass - the candidate target class
Returns:
whether the advice should apply to the given target class

matches

public boolean matches(Method method,
                       Class targetClass,
                       boolean beanHasIntroductions)
Description copied from interface: IntroductionAwareMethodMatcher
Perform static checking whether the given method matches. This may be invoked instead of the 2-arg MethodMatcher.matches(java.lang.reflect.Method, Class) method if the caller supports the extended IntroductionAwareMethodMatcher interface.

Specified by:
matches in interface IntroductionAwareMethodMatcher
Parameters:
method - the candidate method
targetClass - the target class (may be null, in which case the candidate class must be taken to be the method's declaring class)
beanHasIntroductions - true if the object on whose behalf we are asking is the subject on one or more introductions; false otherwise
Returns:
whether or not this method matches statically

matches

public boolean matches(Method method,
                       Class targetClass)
Description copied from interface: MethodMatcher
Perform static checking whether the given method matches. If this returns false or if the MethodMatcher.isRuntime() method returns false, no runtime check (i.e. no. MethodMatcher.matches(java.lang.reflect.Method, Class, Object[]) call) will be made.

Specified by:
matches in interface MethodMatcher
Parameters:
method - the candidate method
targetClass - the target class (may be null, in which case the candidate class must be taken to be the method's declaring class)
Returns:
whether or not this method matches statically

isRuntime

public boolean isRuntime()
Description copied from interface: MethodMatcher
Is this MethodMatcher dynamic, that is, must a final call be made on the MethodMatcher.matches(java.lang.reflect.Method, Class, Object[]) method at runtime even if the 2-arg matches method returns true?

Can be invoked when an AOP proxy is created, and need not be invoked again before each method invocation,

Specified by:
isRuntime in interface MethodMatcher
Returns:
whether or not a runtime match via the 3-arg MethodMatcher.matches(java.lang.reflect.Method, Class, Object[]) method is required if static matching passed

matches

public boolean matches(Method method,
                       Class targetClass,
                       Object[] args)
Description copied from interface: MethodMatcher
Check whether there a runtime (dynamic) match for this method, which must have matched statically.

This method is invoked only if the 2-arg matches method returns true for the given method and target class, and if the MethodMatcher.isRuntime() method returns true. Invoked immediately before potential running of the advice, after any advice earlier in the advice chain has run.

Specified by:
matches in interface MethodMatcher
Parameters:
method - the candidate method
targetClass - the target class (may be null, in which case the candidate class must be taken to be the method's declaring class)
args - arguments to the method
Returns:
whether there's a runtime match
