  • Method Details

    • deserialize

      public final T deserialize​(javax.json.stream.JsonParser parser, javax.json.bind.serializer.DeserializationContext context, Type rtType)
      Drives JSONP JsonParser to deserialize json document.
      Specified by:
      deserialize in interface javax.json.bind.serializer.JsonbDeserializer<T>
      Parameters:
      parser - JSON parser.
      context - Deseriaization context.
      rtType - Runtime type.
      Returns:
      Instance of a type for this item.

    • getInstance

      protected abstract T getInstance​(Unmarshaller unmarshaller)
      Creates and initializes an instance of deserializing item.
      Parameters:
      unmarshaller - Current deserialization context.
      Returns:
      An instance of deserializing item.

    • deserializeInternal

      protected void deserializeInternal​(JsonbParser parser, Unmarshaller context)
      Deserialize specific item type.
      Parameters:
      parser - jsonb parser
      context - context

    • deserializeNext

      protected abstract void deserializeNext​(javax.json.stream.JsonParser parser, Unmarshaller context)
      Determine class mappings and create an instance of a new deserializer. Currently processed deserializer is pushed to stack, for waiting till new object is finished.
      Parameters:
      parser - Json parser.
      context - Current unmarshalling context.

    • moveToFirst

      protected abstract JsonbRiParser.LevelContext moveToFirst​(JsonbParser parser)
      Move to first event for current deserializer structure.
      Parameters:
      parser - Json parser.
      Returns:
      First event.

    • newUnmarshallerItemBuilder

      protected DeserializerBuilder newUnmarshallerItemBuilder​(JsonbContext ctx)
      Returns new deserialization builder for specific item.
      Parameters:
      ctx - jsonb context
      Returns:
      deserialization builder

    • newCollectionOrMapItem

      protected javax.json.bind.serializer.JsonbDeserializer<?> newCollectionOrMapItem​(Type valueType, JsonbContext ctx)
      Returns new deserialization builder for specific collection or map.
      Parameters:
      valueType - value type
      ctx - jsonb context
      Returns:
      deserialization builder

    • convertNullToOptionalEmpty

      protected Object convertNullToOptionalEmpty​(Type propertyType, Object value)
      If value is null and property model type is one of Optional, OptionalDouble, OptionalInt, or OptionalLong, value of corresponding Optional#empty() is returned.
      Parameters:
      propertyType - property type
      value - value to set
      Returns:
      empty optional if applies

    • appendResult

      public abstract void appendResult​(Object result, Unmarshaller context)
      After object is transitively deserialized from JSON, "append" it to its wrapper. In case of a field set value to field, in case of collections or other embedded objects use methods provided.
      Parameters:
      result - An instance result of an item.
      context - Current unmarshalling context.
