RCP 3.x register alternate service implementation with locator [message #1699824] Fri, 26 June 2015 21:19 Go to next message

I have a need where I have a multiple versions of our RCP application, the base version is somewhat generic, and others contain domain specific enhancements to core functionality. In this case we have a parser which provided via a service. The domain specific parser, which is located in a different plug-in, but extends the base verion, implements the same service interface, but provides additional information in the parsed content.

The basic parser is registered declaratively within the plugin.xml. How should I register the enhanced version? It looks like I can register the the enhanced service version via the ServiceLocator which will overwrite any existing, but understanding that I can't exactly control the plug-in load order, how do I prevent the basic parser to now overwrite the enhanced parser? Do I need to alter the way it gets registered as well?

Thanks!

Consider making your parsers available via OSGi Services instead. The spec provides for prioritizing services by using the "service.ranking" property. If unspecified, the service.ranking defaults to 0. The service.ranking is used by BundleContext#getServiceReference() to return the 'best' instance, and you can check it too.

Alternatively, specify your own ranking in your extension point schema to provide for other parser definitions to override your basic definition.
