Re: Aspect logging in Guice?

[Stephan Classen]

For implementing your own matcher AbstractMatcher would be a good start. i.e. public class MyMatcher extends AbstractMatcher<Method> {     public boolean matches(Method method) {         // your code here     } } Note: the above can only match methods. if it should also be able to match classes make your matcher extend one of the following:  - AbstractMatcher<AnnotatedElement>  - AbstractMatcher<GenericDeclaration>  - AbstractMatcher<Object> On 10/11/2012 04:42 PM, Rob Withers wrote: I did find the Annotations solution.   What would my own Matcher look like, perhaps using reflection and AspectJ expressions to specify methods?  Is there such a duck out there?   Thanks, Rob   From: google-guice@googlegroups.com [mailto:google-guice@googlegroups.com] On Behalf Of Stephan Classen Sent: Thursday, October 11, 2012 2:46 AM To: google-guice@googlegroups.com Subject: Re: Aspect logging in Guice?   You can write your own matche and use it instead of passing Matchers.any(). Or if it is ok for you to annotate the methods which you want to intercept you can use the existing Matchers.annotatedWith(...)
