[ https://issues.jboss.org/browse/FORGE-226?page=com.atlassian.jira.plugin.... ] Ken Finnigan commented on FORGE-226: ------------------------------------ Discussion on irc: (03:38:13 PM) lincolnthree: imagine you have a PomXmlResource (there is such a thing in Forge 1) (03:38:16 PM) lincolnthree: you could say: (03:38:31 PM) lincolnthree: pomResource.getFacet(ProfilesFacet.class) (03:38:53 PM) lincolnthree: So in a sense, a project would just be a Resource! (03:39:32 PM) kenfinnigan: so if I understand it.. (03:39:34 PM) lincolnthree: webXmlResource.getFacet(ServletsFacet.class) (03:39:46 PM) kenfinnigan: JavaSourceResource.getFacet(EJBFacet.class).isBeanType(Type.MESSAGE_DRIVEN_BEAN) (03:39:55 PM) lincolnthree: webXmlResource.hasFacet(ContextParamsFacet.class) (03:39:56 PM) kenfinnigan: would return an EJB that was an MDB? (03:40:01 PM) lincolnthree: right (03:40:05 PM) kenfinnigan: ie the java source of the class that is (03:40:10 PM) lincolnthree: well (03:40:17 PM) lincolnthree: based on what you've written, i'd expect it to return a boolean (03:40:18 PM) lincolnthree: but (03:40:19 PM) lincolnthree: yes (03:40:42 PM) lincolnthree: javaResource.hasFacet(ArquillianFacet.class) (03:40:44 PM) lincolnthree: etc (03:41:22 PM) kenfinnigan: ok, I was reading JavaSourceResource as a static, but from what you're saying in that example it would actually be an instance (03:41:26 PM) kenfinnigan: correct? (03:41:44 PM) kenfinnigan: so asking that java source instance if it's an MDB (03:41:47 PM) lincolnthree: javaResource.getFacet(TransactionInterceptorFacet.class).getPropagationType(); (03:41:56 PM) lincolnthree: it would be an instance (03:41:57 PM) lincolnthree: yes (03:42:04 PM) kenfinnigan: ok (03:42:21 PM) lincolnthree: so the facet would be able to inspect/install/remove certain pieces of information from java code in this case (03:42:30 PM) lincolnthree: in a very granular/controlled manner (03:42:55 PM) kenfinnigan: hmm, so where would that control lie, in the Facet or Resource, or bit of both? (03:44:42 PM) lincolnthree: the resource would have no knowledge of the facets contained within (03:44:54 PM) lincolnthree: facets would be responsible for inspecting the resource and determining their own installation sate (03:44:56 PM) lincolnthree: state (03:44:59 PM) lincolnthree: just like Project facets (03:45:07 PM) aslak: kenfinnigan, what am i saying? :) (03:45:24 PM) kenfinnigan: ok, so Resource just needs to provide the means that Facet can do the kinds of things aslak wants? (03:45:29 PM) kenfinnigan: aslak: FORGE-226 (03:45:30 PM) jbossbot: jira [FORGE-226] Support for Facets construct on Resources [Open (Unresolved) Feature Request, Major, Unassigned] https://issues.jboss.org/browse/FORGE-226 (03:45:39 PM) lincolnthree: resource needs to provide a generic Facet API (03:45:47 PM) lincolnthree: like the Project class in forge 1.x does (03:45:47 PM) kenfinnigan: lincolnthree: ok (03:46:18 PM) lincolnthree: https://github.com/forge/core/blob/master/shell-api/src/main/java/org/jbo... (03:46:31 PM) lincolnthree: something like that (03:46:39 PM) aslak: kenfinnigan, aa.. the basic idea is.. you have Facets on a Project (capabilities for a given project), the similar thing you would have on Resource level (03:47:15 PM) aslak: new XMLResource("arquillian.xml").getFacet(ArquillianFacet.class).addContainer() (03:47:51 PM) kenfinnigan: aslak: ok, so then the ArquillianFacet "knows" the correct XML to add back to the resource for addContainer()? (03:48:00 PM) aslak: yes (03:48:30 PM) kenfinnigan: ok, so Facets do all the work of modifying Resource, but Resource needs to know what kind of Facet it can deal with (03:48:33 PM) aslak: you need a 'supports(Facet)" or similar in ther ea swell (03:48:47 PM) aslak: it's basically a way to share code on resource level instead of just project level (03:48:59 PM) lincolnthree: yea (03:48:59 PM) kenfinnigan: ok, think that makes sense (03:49:18 PM) aslak: the EJB addon should know 'stuff' about a Class to determine if it's a EJB.. possible add EJB related annotations -- This message is automatically generated by JIRA.
