OpcData Class

Namespace: Opc.UaFx
Assemblies: Opc.UaFx.Advanced.dll

Defines an abstract base class of data objects used and provided in the ecosystem of a specific OPC UA Server.

C# 

[OpcDataType(22)]
public abstract class OpcData


Inheritance Object › OpcData


Derived


Attributes OpcDataTypeAttribute

Constructors

Name Description
OpcData Initializes a new instance of the OpcData class.
OpcData(IOpcDataStore) Initializes a new instance of the OpcData class using the dataStore specified.

Events

Name Description
TypeResolve Occurs when the resolution of a data type fails. Use this event to manually provide the Type to use for a specific data type definition identifier.

Properties

Name Description
DataStore Gets the IOpcDataStore which contains the data of this OpcData instance.

Methods

Name Description
Decode``1(OpcContext, Byte) Converts the buffer specified to the T defined.
Decode``1(OpcContext, Stream) Converts the data in the stream specified to the T defined.
