inline

The default constructor.

Member Function Documentation

virtual bool UnifiedAutomation.UaBase.ModelChangeStructureDataType.IsEqual ( IEncodeable  encodeable)

Checks if encodeable is the same object or has the same content

Parameters
encodeable
Returns

Implements UnifiedAutomation.UaBase.IEncodeable.

Property Documentation

NodeId UnifiedAutomation.UaBase.ModelChangeStructureDataType.Affected
getset

NodeId of the Node that was changed.

The client should assume that the affected Node has been created or deleted, had a Reference added or deleted, or the DataType has changed as described by the verb.

NodeId UnifiedAutomation.UaBase.ModelChangeStructureDataType.AffectedType
getset

If the affected Node was an object or Variable, affectedType contains the NodeId of the TypeDefinitionNode of the affected Node. Otherwise it is set to null.

byte UnifiedAutomation.UaBase.ModelChangeStructureDataType.Verb
getset

Describes the changes happening to the affected Node.

The verb is an 8-bit unsigned integer used as bit mask with the structure defined in the following table:

Field Bit Description
NodeAdded 0 Indicates the affected Node has been added.
NodeDeleted 1 Indicates the affected Node has been deleted.
ReferenceAdded 2 Indicates a Reference has been added. The affected Node may be either a SourceNode or TargetNode. Note that an added bidirectional Reference is reflected by two ChangeStructures.
ReferenceDeleted 3 Indicates a Reference has been deleted. The affected Node may be either a SourceNode or TargetNode. Note that a deleted bidirectional Reference is reflected by two ChangeStructures.
DataTypeChanged 4 This verb may be used only for affected Nodes that are Variables or VariableTypes. It indicates that the DataType Attribute has changed.
Reserved 5:7 Reserved for future use. Shall always be zero.

A verb may identify several changes on the affected Node at once. This feature should be used if event compression is used.

Note that all verbs shall always be considered in the context where the ModelChangeStructureDataType is used. A NodeDeleted may indicate that a Node was removed from a view but still exists in other Views.
