public abstract class StaticMethodMatcher
extends java.lang.Object
implements MethodMatcher

Method Detail

isRuntime

public final 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 final boolean matches(java.lang.reflect.Method method,
                             java.lang.Class<?> targetClass,
                             java.lang.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
