类 ControlFlowPointcut
- java.lang.Object
- org.springframework.aop.support.ControlFlowPointcut
- 所有已实现的接口:
Serializable,ClassFilter,MethodMatcher,Pointcut
public class ControlFlowPointcut extends Object implements Pointcut, ClassFilter, MethodMatcher, Serializable
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.- 作者:

ControlFlowPointcut
public ControlFlowPointcut(Class<?> clazz)
Construct a new pointcut that matches all control flows below that class.- 参数:
clazz- the clazz
ControlFlowPointcut
public ControlFlowPointcut(Class<?> clazz, @Nullable String methodName)
Construct a new pointcut that matches all calls below the given method in the given class. If no method name is given, matches all control flows below the given class.- 参数:
clazz- the clazzmethodName- the name of the method (may benull)
方法详细资料
matches
public boolean matches(Class<?> clazz)
Subclasses can override this for greater filtering (and performance).- 指定者:
matches在接口中ClassFilter- 参数:
clazz- the candidate target class- 返回:
- whether the advice should apply to the given target class
matches
public boolean matches(Method method, Class<?> targetClass)
Subclasses can override this if it's possible to filter out some candidate classes.- 指定者:
matches在接口中MethodMatcher- 参数:
method- the candidate methodtargetClass- the target class- 返回:
- whether or not this method matches statically
isRuntime
public boolean isRuntime()
从接口复制的说明:MethodMatcherIs this MethodMatcher dynamic, that is, must a final call be made on theMethodMatcher.matches(java.lang.reflect.Method, Class, Object[])method at runtime even if the 2-arg matches method returnstrue?Can be invoked when an AOP proxy is created, and need not be invoked again before each method invocation,
- 指定者:
isRuntime在接口中MethodMatcher- 返回:
- 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)
从接口复制的说明:MethodMatcherCheck 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
truefor the given method and target class, and if theMethodMatcher.isRuntime()method returnstrue. Invoked immediately before potential running of the advice, after any advice earlier in the advice chain has run.- 指定者:
matches在接口中MethodMatcher- 参数:
method- the candidate methodtargetClass- the target classargs- arguments to the method- 返回:
- whether there's a runtime match

MethodMatcher.matches(Method, Class)
getEvaluations
public int getEvaluations()
It's useful to know how many times we've fired, for optimization.
getClassFilter
public ClassFilter getClassFilter()
从接口复制的说明:PointcutReturn the ClassFilter for this pointcut.- 指定者:
getClassFilter在接口中Pointcut- 返回:
- the ClassFilter (never
null)
getMethodMatcher
public MethodMatcher getMethodMatcher()
从接口复制的说明:PointcutReturn the MethodMatcher for this pointcut.- 指定者:
getMethodMatcher在接口中Pointcut- 返回:
- the MethodMatcher (never
null)
