Class MethodMatchers

  • java.lang.Object
    • org.springframework.aop.support.MethodMatchers


  • public abstract class MethodMatchers
    extends java.lang.Object
    Static utility methods for composing MethodMatchers.

    A MethodMatcher may be evaluated statically (based on method and target class) or need further evaluation dynamically (based on arguments at the time of method invocation).

        public static boolean matches(MethodMatcher mm,
                                      java.lang.reflect.Method method,

                                      boolean hasIntroductions)
        Apply the given MethodMatcher to the given Method, supporting an IntroductionAwareMethodMatcher (if applicable).
        Parameters:
        mm - the MethodMatcher to apply (may be an IntroductionAwareMethodMatcher)
        method - the candidate method
        targetClass - the target class
        hasIntroductions - 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
