    public static JsonMacaddrReaderWriter Instance { get; }

#### Property Value

JsonMacaddrReaderWriter

## Methods

### FromJsonTyped(ref Utf8JsonReaderManager, object?)

Reads the value from JSON.

    public override PhysicalAddress FromJsonTyped(ref Utf8JsonReaderManager manager, object? existingObject = null)

#### Parameters

`manager` Utf8JsonReaderManager

  The Utf8JsonReaderManager for the JSON being read.

`existingObject` object

  Can be used to update an existing object, rather than create a new one.

#### Returns

PhysicalAddress

  The read value.

#### Remarks

The CurrentReader is at the node that contains the value to be read. The value should be read as appropriate from the JSON, and then further converted as necessary.

Nulls are handled externally to this reader. That is, this method will never be called if the JSON value is "null".

In most cases, the value is represented in the JSON document as a simple property value--e.g. a number, boolean, or string. However, it could be an array or sub-document. In this case, the Utf8JsonReaderManager should be used to parse the JSON as appropriate.

### ToJsonTyped(Utf8JsonWriter, PhysicalAddress)

Writes the value to JSON.

    public override void ToJsonTyped(Utf8JsonWriter writer, PhysicalAddress value)

#### Parameters

`writer` Utf8JsonWriter

  The Utf8JsonWriter into which the value should be written.

`value` PhysicalAddress

  The value to write.
