Event data class for the OPC UA event type GeneralModelChangeEventType.
This class provides the functionality necessary to create an event of type GeneralModelChangeEventType, to set the values of the event fields and to send the event to interested clients through EventManagerBase::fireEvent().
Event Fields of the GeneralModelChangeEventType:
Browse Name | DataType | TypeDefinition | Modelling Rule | See Also |
---|---|---|---|---|
Changes | ModelChangeStructureDataType | PropertyType | Mandatory | getChanges, setChanges |
Contains information about the Node that was changed and the action that occurred to cause the ModelChangeEvent (e.g. add a Node, delete a Node, etc.).
If the affected Node is a Variable or object, then the TypeDefinitionNode is also present.
To allow Event compression, a GeneralModelChangeEvent contains an array of changes.
This EventType inherits all Properties of the BaseModelChangeEventType.
Two types of ModelChangeEvents are defined: the BaseModelChangeEvent that does not contain any information about the changes and the GeneralModelChangeEvent that identifies the changed Nodes via an array. The precision used depends on both the capability of the OPC UA Server and the nature of the update. An OPC UA Server may use either ModelChangeEvent type depending on circumstances. It may also define subtypes of these EventTypes adding additional information. To ensure interoperability, one should follow the guidelines for Events listed below.
If a Client is not capable of interpreting additional information of the subtypes of the BaseModelChangeEventTypeData, it should treat Events of these types the same way as Events of the BaseModelChangeEventTypeData.
See also GeneralModelChangeEventType for a documentation of the complete Information Model.
void OpcUa::GeneralModelChangeEventTypeData::getChanges | ( | UaModelChangeStructureDataTypes & | Changes | ) |
Get the event field value Changes.
Reflects the changes that issued the ModelChangeEvent.
It shall contain at least one entry in its array.
|
virtual |
Get the event field value Changes for delivering the event data.
This method can be overwritten in a derived class to return a client session specific value like a localized text matching the LocaleId requested by the client
Reflects the changes that issued the ModelChangeEvent.
It shall contain at least one entry in its array.
|
virtual |
Get the field value for the passed index.
index | The index of the selected field. |
pSession | The session context for the method call. |
data | The data for the selected field. |
Reimplemented from OpcUa::BaseModelChangeEventTypeData.
void OpcUa::GeneralModelChangeEventTypeData::setChanges | ( | const UaModelChangeStructureDataTypes & | Changes | ) |
Set the event field value Changes.
Reflects the changes that issued the ModelChangeEvent.
It shall contain at least one entry in its array.
void OpcUa::GeneralModelChangeEventTypeData::setChangesStatus | ( | OpcUa_StatusCode | status | ) |
Set a status code for the event field value Changes.
If an event field is not available, a StatusCode must be provided instead of the value to indicate the error situation.
