I have worked on a couple of sf projects (user orangeherbert): first, Romain Guy's now-defunct Java text editor Jext and its associated plugins project. More recently, for a very short time, I worked on Dozer, an sf-hosted library with similar goals to Morph but nowhere near the code quality level. It is possible that Morph's much prettier design might equal a performance deficiency compared to Dozer (Dozer had pretty good performance going for it) but truly I doubt that Dozer's huge if-else-else constructs are going to be way faster than Morph's "good OO" polymorphic approach. ;) I'm just getting into Morph, however, so haven't really been able to put its performance to the test. Beyond sourceforge, I am a member of the Apache Ant Project Management Committee, and that's where my main body of OSS experience lies. Apache is a cool community IMHO but moving Morph there would be a pain: incubation process, etc. though it might be a possibility to consider in the future. I am pretty low in the overall Apache pecking order, but some of the other folks at Ant are a little higher up. Not sure if any of them have a vested interest in a library like Morph. :| > > Can you describe the bug you found in the software? > It's possible I've > already prepared a fix but not released it. > First, let me explain that I tend to read OSS code before ever trying to run against it, just one of my personal idiosyncrasies... I like to know what to expect. So I was browsing back and forth through the API docs and ended up reading the ChainedConverter code. What I found was that it didn't properly implement ExplicitTransformer. How I proved this was to write a small converter that uses a TypeMap to implement ExplicitTransformer. I created two instances with the following mappings: instance 1: A.class=B.class, B.class=C.class instance 2: B.class=C.class, D.class=E.class All five of these classes are just simple extensions of Object with no body. I chained these two instances together with a ChainedConverter; we'll call it "cc". Now, you can see that, for example, A is transformable to C because instance 1 can transform A to B and instance 2 can transform B to C. Thus cc.isTransformable(C.class, A.class) == true. But because ChainedConverter simply inherits the default isTransformableImpl from BaseTransformer, cc.isTransformable(E.class, A.class) == true also, but it is obvious by looking at the configuration that this is not true. I have this setup in a junit TestCase. Further, I have just built and tested the morph-1.0.1 release, and get 132 of 732 tests failed. :( -Matt B. > Matt > > Matt Benson wrote: > > Morph looks very promising, but I am pretty sure I > > already have a bug to report. ;) What's the best > way > > to get involved with this apparently slightly > dormant > > project, or do I need to fork my own version? :( > > > > br, > > Matt > > > > __________________________________________________ > > Do You Yahoo!? > > Tired of spam?
