[MDSAL-792] Union value classes need to enforce non-null components

Wed, 9 Nov 2022 21:05:28 +0000

We have the following code generated here:

        public VlanId(Id _id) {
            super();
            this._id = _id;
            this._enumeration = null;
        }
        
        public VlanId(Enumeration _enumeration) {
            super();
            this._enumeration = _enumeration;
            this._id = null;
        }

in org.opendaylight.yang.gen.v1.urn.test.rev170101.Cont.java.

This works in general, but it allows invalid objects to be created – if the argument is null, we end up with a union which is neither one or the other:

        public VlanId(Id _id) {
            super();
            this._id = Objects.requireNonNull(_id);
            this._enumeration = null;
        }
        
        public VlanId(Enumeration _enumeration) {
            super();
            this._enumeration = Objects.requireNonNull(_enumeration);
            this._id = null;
        }
