hello,

I want to write all the possible scenarios of java class definition, one of them is the implementing of interface.. I tried multiple options but it seems that it did not work correctly..
can you give some hints.

the definition I want to write e.g.

foreach implmented interface / list of interfaces

public class ClassName extends MyClass implements MyInterface/ListOfInterfaces {}

the question is about the underlined text..

Thanx in-advance!

Hello,

can you tell more about the context you are asking the question within. which metamodel are you using? which templates do you use at to moment?

hello,

I am using UML for modeling. I managed to get all elements for class definition like

«visibility» class «name-» «IF !superClass.isEmpty» extends «superClass.first().name» «ENDIF» {}

If the class implements one or more interfaces how can I extract it/them from the model automatically?

Hello this.interfaceRealization.contract delivers a list of implemented interfaces of an uml::Class. see Chapter 7.3.25 of OMG Unified Modeling LanguageTM (OMG UML),
Superstructure for more information. You can find the document (here)

it works but it displays the brackets [, ]
do you know how to ignore them?

it returns the same output as getAllImplementedInterfaces()...!

thanx for your patience and help.

hi that is the behaviour of all lists in xpand if you just output them as they are. you have to use foreach or something like this to generate code e.g. something like this one:

«IF this.interfaceRealization.contract.size > 0»implements «FOREACH this.interfaceRealization.contract AS i SEPARATOR ","»«i.name»«ENDFOREACH»«ENDIF»

if you only want to remove the brackets, its easy using Xtend:

String withoutBrackets (String s) :
s.replaceAll("[\\[\\]]","");

but as Christian told you the correct way is using a FOREACH construct

I'm using the withoutBrackets() extension per ex. while logging the
content of a list

Or a bit more concise:
«interfaceRealization.contract.name.toString(',')»
