java.lang.Object org.springframework.aop.support.ControlFlowPointcut
public class ControlFlowPointcut
Pointcut and method matcher for use in simple cflow-style pointcut. Note that evaluating such pointcuts is 10-15 times slower than evaluating normal pointcuts, but they are useful in some cases.

ControlFlowPointcut(Class clazz)
Construct a new pointcut that matches all control flows below that class. |
|
ControlFlowPointcut(Class clazz,
String methodName)
Construct a new pointcut that matches all calls below the given method in the given class. |

ClassFilter |
getClassFilter()
Return the ClassFilter for this pointcut. |
int |
getEvaluations()
It's useful to know how many times we've fired, for optimization. |
MethodMatcher |
getMethodMatcher()
Return the MethodMatcher for this pointcut. |
int |
hashCode()
|
boolean |
isRuntime()
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 ? |
boolean |
matches(Class clazz)
Subclasses can override this for greater filtering (and performance). |
boolean |
matches(Method method,
Class targetClass)
Subclasses can override this if it's possible to filter out some candidate classes. |
boolean |
matches(Method method,
Class targetClass,
Object[] args)
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

method returns true
. Invoked
immediately before potential running of the advice, after any
advice earlier in the advice chain has run.
