      • expectNextEvent

        public static jakarta.json.stream.JsonParser.Event expectNextEvent​(jakarta.json.stream.JsonParser parser,
                                                                   jakarta.json.stream.JsonParser.Event expected)
        Advances the parser to the next event and checks that this even is the expected one.
        Returns:
        the expected event
        Throws:
        jakarta.json.JsonException - if an i/o error occurs (IOException would be cause of JsonException)
        jakarta.json.stream.JsonParsingException - if the event is not the expected one, or if the parser encounters invalid JSON when advancing to next state.
        java.util.NoSuchElementException - if there are no more parsing states.

        Looks ahead a field value in the Json object from the upcoming object in a parser, which should be on the START_OBJECT event. Returns a pair containing that value and a parser that should be used to actually parse the object (the object has been consumed from the original one).
