      • migrateViewEcoreNsUri

        public static boolean migrateViewEcoreNsUri​(java.io.File file)
                                     throws java.io.IOException
        If the given file references the view ecore, migrate the view ecore namespace URI of the template model to the namespace URI of the registered version of the view ecore. This is necessary for domain model reference selectors to be compatible to the view models of the current version. Thereby, we assume that view models use the registered version of the view ecore because otherwise they could not be used in the current runtime environment.

        Note: If no migration is necessary, nothing is written to the output writer.

        Parameters:
        file - The File containing the template model
        Returns:
        whether the namespace uri was migrated
        Throws:
        java.io.IOException - if something goes wrong reading or writing the template model file
