      • getClass

        public java.lang.Class<? extends NamedObj> getClass​(java.lang.String className,
                                                    VersionSpecification versionSpec)
                                             throws java.lang.ClassNotFoundException
        Return the requested class for the requested version (if specified).

        If this provider doesn't have this class available, it should throw a ClassNotFoundException. (Optionally, it could also just return null, for those dvp-ers who don't like exceptions. ;-) )

        Specified by:
        getClass in interface ModelElementClassProvider
        Parameters:
        className - typically a fully qualified Java class name. Mandatory non-null.
        versionSpec - optional constraint on desired version for the class that must be provided. If null, no version constraint is imposed.
        Returns:
        the concrete class of the NamedObj matching the given className.
        Throws:
        java.lang.ClassNotFoundException - if this provider can not provide the requested class for the requested version (if specified).
