  • Field Details

    • MAX_TO_STRING_LENGTH

      @Deprecated public static int MAX_TO_STRING_LENGTH
      Deprecated.
      use maxToStringLength(int)

  • Method Details

    • provider

      public static jakarta.json.spi.JsonProvider provider()
      Get a JsonProvider instance. This method first calls the standard `JsonProvider.provider()` that is based on the current thread's context classloader, and in case of failure tries to find a provider in other classloaders.

    • 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

      public static void expectEvent​(jakarta.json.stream.JsonParser parser, jakarta.json.stream.JsonParser.Event expected, jakarta.json.stream.JsonParser.Event event)

    • expectKeyName

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

    • ensureAccepts

      public static void ensureAccepts​(JsonpDeserializer<?> deserializer, 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.

    • 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, java.lang.String defaultValue, 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).

    • objectParser

      public static jakarta.json.stream.JsonParser objectParser​(jakarta.json.JsonObject object, JsonpMapper mapper)
      Create a parser that traverses a JSON object

    • toString

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

    • serializeDoubleOrNull

      public static void serializeDoubleOrNull​(jakarta.json.stream.JsonGenerator generator, double value, double defaultValue)

    • serializeIntOrNull

      public static void serializeIntOrNull​(jakarta.json.stream.JsonGenerator generator, int value, int defaultValue)

    • toString

      public static java.lang.String toString​(JsonpSerializable value)
      Renders a JsonpSerializable as a string by serializing it to JSON, prefixed by the class name. Any object of an application-specific class in the object graph is rendered using that object's toString() representation as a JSON string value.

      The size of the string is limited to maxToStringLength().

      See Also:
      maxToStringLength()

    • maxToStringLength

      public static void maxToStringLength​(int length)
      Set the maximum length of the JSON representation of a JsonpSerializable in the result of its toString() method. The default is 10k characters.

    • maxToStringLength

      public static int maxToStringLength()
      Get the maximum length of the JSON representation of a JsonpSerializable in the result of its toString() method. The default is 10k characters.

    • toString

      public static java.lang.StringBuilder toString​(JsonpSerializable value, JsonpMapper mapper, java.lang.StringBuilder dest)
      Renders a JsonpSerializable as a string in a destination StringBuilderby serializing it to JSON.

      The size of the string is limited to maxToStringLength().

      Returns:
      the dest parameter, for chaining.
