/**
 * A subscribable message field which can be passed to subscription filters.
 *
 * <p>Normally this type shouldn't be inherited in the client code and is instead used by the
 * Spine routines which provide generated field enumerations.
 *
 * <p>See the {@code Fields} class in the subscribable message declarations.
 *
 * @apiNote Among others, this class is normally inherited by the nested field containers, which
 *        expose nested message fields as public instance methods, for example:
 *        <pre>
 *        public EntityStateField someFieldName() {...}
 *        </pre>
 *        Thus, this class has to avoid name clashes with proto fields declared this way. Hence the
 *        otherwise redundant "get-" prefix on the {@link #getField()} method. For the same reason
 *        the class does not inherit from {@link io.spine.value.ValueHolder}.
