[Oorexx-devel] Questions ad an object being used by a different RexxInstance ...
Given two different RexxInstances R1 and R2 running in the same process. In R1 an object O1 is created and saved in .environment. Two questions ad RexxInterpreter context: 1. If from R2 an interaction occurs with O1 (addressed via .environment), in which context does O1 execute, in R1 (the creator RexxInterpreterInstance) or in R2 (the invoker RexxInterpreterInstance)? 2. If R1 is terminated, but R2 interacts with O1 (addressed via .environment), in which context does O1 execute, in R1 (the creating RexxInterpreterInstance, but terminated) or in R2 (the invoking RexxInterpreterInstance)? ---rony -- Crystal Reports #45; New Free Runtime and 30 Day Trial Check out the new simplified licensign option that enables unlimited royalty#45;free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects___ Oorexx-devel mailing list Oorexx-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/oorexx-devel

I'm not sure this question makes any sense. An interaction on an object occurrs in the context of where the interaction is triggered. Objects are just data, and have no knowledge of where they have been created. If one instance stores an object in .environment (generally a bad practice), then it is just an object that's available for any instance. It will remain alive until the global Rexx environment is terminated. Rick On Sun, Apr 26, 2009 at 6:32 AM, Rony G.

If one instance stores an object in .environment (generally a bad practice), then it is just an object that's available for any instance. It will remain alive until the global Rexx environment is terminated. The reason for asking is this: if having multiple RexxInterpreterInstances running for different Java objects, and if one wishes to allow Java to interact with proxy Rexx objects (in the JNI layer), do I have to use the cached RexxInterpreterInstance (in the JNI layer) from which the proxied Rexx objects come from originally, or is it o.k. to use any present RexxInterpreterInstance to attach to and then forwarding the Rexx proxy object messages from Java. This is about contemplating of allowing Java to interact with Rexx objects in a general way (not only for event handlers) and sending them messages. If I understood your answer correctly, then it does not matter which RexxInterpreterInstance I would use to send messages to cached (in the JNI layer) Rexx objects. (Also assuming, that once all RexxInterpreterInstances got terminated, no such invocation should be allowed anymore, but throw an exception.) ---rony -- Crystal Reports #45; New Free Runtime and 30 Day Trial Check out the new simplified licensign option that enables unlimited royalty#45;free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects ___ Oorexx-devel mailing list Oorexx-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/oorexx-devel
