public interface JsonpDeserializer<V>

  • Method Details

    • nativeEvents

      EnumSet<jakarta.json.stream.JsonParser.Event> nativeEvents()
      The native JSON events this deserializer accepts as a starting point. For example, native events for a boolean are JsonParser.Event.VALUE_TRUE and JsonParser.Event.VALUE_FALSE.

    • acceptedEvents

      EnumSet<jakarta.json.stream.JsonParser.Event> acceptedEvents()
      The JSON events this deserializer accepts as a starting point. For example, events for a boolean are JsonParser.Event.VALUE_TRUE, JsonParser.Event.VALUE_FALSE and JsonParser.Event.VALUE_STRING, the latter being converted to a boolean using Boolean.parseBoolean(String).

    • accepts

      default boolean accepts(jakarta.json.stream.JsonParser.Event event)
      Convenience method for acceptedEvents().contains(event)

    • deserialize

      default V deserialize(jakarta.json.stream.JsonParser parser, JsonpMapper mapper)
      Deserialize a value. The value starts at the next state in the JSON stream.

      Default implementation delegates to deserialize(JsonParser, JsonpMapper, Event) after having checked that the next event is part of the accepted events.

      If the next event is JsonParser.Event.VALUE_NULL, null is returned unless JsonParser.Event.VALUE_NULL is part of the deserializer's accepted events.

      Parameters:
      parser - the JSON parser
      mapper - the JSON-P mapper
      Returns:
      the parsed value or null

    • deserialize

      V deserialize(jakarta.json.stream.JsonParser parser, JsonpMapper mapper, jakarta.json.stream.JsonParser.Event event)
      Deserialize a value. The value starts at the current state in the JSON stream.
      Parameters:
      parser - the JSON parser
      mapper - the JSON-P mapper
      event - the current state of parser, which must be part of acceptedEvents()
      Returns:
      the parsed value
