Method Detail

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)

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

---

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

See Also:

MethodMatcher.matches(Method, Class)

toString

public String toString()

Overrides:

toString in class Object
