Constructors

Name	Description
OpcDataprotected · 2 overloads	Initializes a new instance of the OpcData class.

Properties

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

Methods

Name	Description
Decodestatic · 3 overloads	Converts the buffer specified to the T defined.
DeepCopyprotected · virtual	Creates a copy of the current OpcData, which the SDK uses whenever it copies an encodable value of it.
Encodestatic · 2 overloads · since v2.58	Encodes the value specified using its Binary encoding.
GetDataStoreprotected · virtual · since v2.32	Retrieves the IOpcDataStore which contains the data of this OpcData instance.
GetTypestatic	Retrieves the Type which implementes the data type which is identified by the typeId specified.
GetTypeInfostatic · 4 overloads	Retrieves the OpcDataTypeInfo which declares the data type implemented by the T specified.
Newstatic	Creates a new instance of the OpcDataObject class using the dataType specified.
NewArraystatic	Creates a one-dimensional array of OpcDataObject objects using the dataType and length with zero-based indexing.
RegisterTypestatic · 6 overloads	Registers the type defined by T as the data object type to create in case there a data instance is to be created for the type definition identified by the OpcDataTypeAttribute defined on the T specified.
RegisterTypeMapperstatic · 2 overloads · since v2.27	Registers the T implementing the IOpcDataTypeMapper interface as a custom mapper for data types.
RegisterTypesstatic · 3 overloads	Registers all non-abstract types in the assembly specified which defines the OpcDataTypeAttribute.
ShallowCopyprotected · virtual	Creates a shallow copy of the current OpcData.
ToExtensionstatic · since v2.40	Wraps the instance into an ExtensionObject, so that it can be encoded as the instance of its data type.
TryGetTypeMapperstatic · 3 overloads · since v2.27	Determines the IOpcDataTypeMapper associated with the type specified by TSource.
UnregisterTypestatic · 3 overloads	Unregisters the previously registered (see RegisterType) type defined by T as the object type to not longer create for the type definition identified by the OpcDataTypeAttribute defined on the T specified.
UnregisterTypeMapperstatic · 2 overloads · since v2.27	Unregisters the T implementing the IOpcDataTypeMapper interface as a custom mapper for data types.
UnregisterTypesstatic · 3 overloads	Unregisters all previously registered types (see RegisterTypes) in the assembly specified.

Events

Name	Description
TypeResolvestatic	Occurs when the resolution of a data type fails.
