| [corona-dev] Extension points vs Services. |
|
Comming back to the subject from yesterday's conference. Here is an
extract from Peter Kriens article, an Equinox commiter,
http://www.osgi.org/blog/2006/01/eclipse-corona-project-distributed.html
"Extension points used to have the advantage of lazy initialization, that is, no class loader of the provider was created until the provider was used. Originally extension points were a pure Eclipse feature but the Equinox team has ported this to a bundle so all OSGi Service Platforms can use this mechanism. However, declarative services provide a better solution today, extension point are an Eclipse 2.0 legacy. " It seems that even though we use extension points, it can be used by any OSGi plantform if it uses the bundle for it. But should we rather use declarative services? I'm not that much into declarative services, but based on what I know it seems that extension points have more power in terms of "lazy initialization".
