| Name | Description |
|---|---|
| [DefaultBinary](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcencoding/members#defaultbinary)<span class="api-meta">static</span> | Gets the foundation defined encoding used by default to encode information using the binary representation (known as 'OPC UA Binary') of the information to serialize or deserialize. |
| [DefaultXml](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcencoding/members#defaultxml)<span class="api-meta">static</span> | Gets the foundation defined encoding used by default to encode information using a XML-based serialization format (known as 'OPC UA XML') to serialize or deserialize information. |
| [Id](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcencoding/members#id) | Gets the identifier of the node which refers to a specific [OpcEncodingType](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcencodingtype/) (defined by [Type](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcencoding/members#type)) used to encode information. |
| [Namespace](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcencoding/members#namespace) | Gets the namespace within the encoding has been defined. |
| [Type](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcencoding/members#type) | Gets a value which identifies the underlying logic used to encode information. |
