NullMetaListConverter¶

Namespace: MQTT_Receiver_Worker

Custom JSON converter for List<TempSensorReading> that converts lists containing only null values to null.
This converter ensures that during JSON deserialization, if a meta list contains only null entries,
the entire list is set to null instead of maintaining a list of null objects.

public class NullMetaListConverter : System.Text.Json.Serialization.JsonConverter`1[[System.Collections.Generic.List`1[[MQTT_Receiver_Worker.MQTT.Models.TempSensorReading, MQTT-Receiver-Worker, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], System.Private.CoreLib, Version=9.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]]

Methods¶

Read(ref Utf8JsonReader, Type, JsonSerializerOptions)¶

Reads and converts the JSON to a List<TempSensorReading>.
If the resulting list contains only null values, returns null instead of the list.

public List<TempSensorReading> Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)

Parameters¶

reader Utf8JsonReader&

The Utf8JsonReader to read from

typeToConvert Type

The type to convert (List<TempSensorReading>?)

options JsonSerializerOptions

The JsonSerializerOptions to use during deserialization

Returns¶

A List<TempSensorReading> containing the deserialized values, or null if the list
was empty, null, or contained only null values

Write(Utf8JsonWriter, List<TempSensorReading>, JsonSerializerOptions)¶

Writes the List<TempSensorReading> to JSON.
Uses the default serialization behavior without any custom logic.

public void Write(Utf8JsonWriter writer, List<TempSensorReading> value, JsonSerializerOptions options)

Parameters¶

writer Utf8JsonWriter

The Utf8JsonWriter to write to

value List<TempSensorReading>

The List<TempSensorReading> value to serialize

options JsonSerializerOptions

The JsonSerializerOptions to use during serialization
