public Optional<LabelSelector> selector() {
        return Optional.ofNullable(this.selector);
    }
@return selector can be used to match multiple param objects based on their labels. Supply selector: {} to match all resources of the ParamKind.

If multiple params are found, they are all evaluated with the policy expressions and the results are ANDed together.

One of `name` or `selector` must be set, but `name` and `selector` are mutually exclusive properties. If one is set, the other must be unset.
