| Re: [gemoc-dev] link between aspects and eObjects |

Hi in K3 aspect instances are hidden, everything is available throught the static methods applied to the EObject itself. The static method takes care to retreive or create the "companion" object and call the code using its data. the link set by Fabien works using java invoke but you can can directly the aspects in pure java if you look at http://diverse-project.github.io/k3/publish/user_documentation/html_single/user_documentation.html#_k3_active_annotations_compilation_example it creates an aspect on java class "File" (but in GEMOC we use it to add aspects on java classes generated from the ecore mm; but it works the same) in the example the line : val f = new File("toto.txt")
f.contentType = "txt"
is possible thanks to the import static extension ....* but actually means(in xtend) val f = new File("toto.txt")
SampleXMLFileAspect.contentType(f, "txt")
which is exactly the same in java (just add ; and correct variable
declaration ;-) )this also works for methods defined in the aspect using a form similar to : MyClassAsspect.myMethod(aspectizedObject, optionalothermethoparameters); I think this would be safer to use since it adds static typing to your code :-) cheers Didier Le 20/06/2018 à 10:13, Julien DeAntoni

Thanks Fabien. I already tried with this helper, from which I can retrieve the Aspect classes, however I'm not able to retrieve the instances of these aspects classes, that are used by the (one of) execution engine... -- Didier Vojtisek SED Rennes - DiverSE Team Univ Rennes, Inria, CNRS, IRISA Campus de beaulieu 35042 Rennes 02 99 84 75 07 |
