public abstract class MethodMatchers
extends Object
extends 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).

Method Detail

union

public static MethodMatcher union(MethodMatcher mm1,
                                  MethodMatcher mm2)

Match all methods that either (or both) of the given MethodMatchers matches.

Parameters:: mm1 - the first MethodMatcher; mm2 - the second MethodMatcher
Returns:: a distinct MethodMatcher that matches all methods that either of the given MethodMatchers matches

intersection

public static MethodMatcher intersection(MethodMatcher mm1,
                                         MethodMatcher mm2)

Match all methods that both of the given MethodMatchers match.

Parameters:: mm1 - the first MethodMatcher; mm2 - the second MethodMatcher
Returns:: a distinct MethodMatcher that matches all methods that both of the given MethodMatchers match

matches

public static boolean matches(MethodMatcher mm,
                              Method method,
                              Class targetClass,
                              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 (may be null, in which case the candidate class must be taken to be the method's declaring 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
