    • 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.

    • expectEvent

    • expectKeyName

      public static java.lang.String expectKeyName​(jakarta.json.stream.JsonParser parser, jakarta.json.stream.JsonParser.Event event)

    • skipValue

      public static void skipValue​(jakarta.json.stream.JsonParser parser)
      Skip the value at the next position of the parser.

    • skipValue

      public static void skipValue​(jakarta.json.stream.JsonParser parser, jakarta.json.stream.JsonParser.Event event)
      Skip the value at the current position of the parser.

    • unknownKey

      public static void unknownKey​(jakarta.json.stream.JsonParser parser, java.lang.String keyName)
      Throws a JsonParsingException because some unknown property name was encountered

    • ensureSingleVariant

      public static java.lang.String ensureSingleVariant​(jakarta.json.stream.JsonParser parser, java.lang.String variant1, java.lang.String variant2)

    • buildVariant

      public static <T> T buildVariant​(jakarta.json.stream.JsonParser parser, ObjectBuilder<T> builder)

    • serialize

      public static <T> void serialize​(T value, jakarta.json.stream.JsonGenerator generator, @Nullable JsonpSerializer<T> serializer, JsonpMapper mapper)

    • lookAheadFieldValue

      public static java.util.Map.Entry<java.lang.String,​jakarta.json.stream.JsonParser> lookAheadFieldValue​(java.lang.String name, jakarta.json.stream.JsonParser parser, JsonpMapper mapper)
      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).

    • toString

      public static java.lang.String toString​(jakarta.json.JsonValue value)
