Detailed Description

Event data class for the OPC UA event type SystemStatusChangeEventType.

This class provides the functionality necessary to create an event of type SystemStatusChangeEventType, to set the values of the event fields and to send the event to interested clients through EventManagerBase::fireEvent().

Event Fields of the SystemStatusChangeEventType:

Browse Name DataType TypeDefinition Modelling Rule See Also
SystemState ServerState PropertyType Mandatory getSystemState, setSystemState

Event that indicates a status change in a system.

For example, if the status indicates that an underlying system is not running, then a Client cannot expect any Events from the underlying system. A Server can identify its own status changes using this EventType.

This EventType inherits all Properties of the SystemEventType. The SourceNode and the SourceName shall identify the system. The system can be the Server itself or some underlying system.

See also SystemStatusChangeEventType for a documentation of the complete Information Model.

Member Function Documentation

void OpcUa::SystemStatusChangeEventTypeData::getFieldData ( OpcUa_UInt32  index,
Session pSession,
OpcUa_Variant data 
)
virtual

Get the field value for the passed index.

Parameters
indexThe index of the selected field.
pSessionThe session context for the method call.
dataThe data for the selected field.

Reimplemented from OpcUa::SystemEventTypeData.

OpcUa_ServerState OpcUa::SystemStatusChangeEventTypeData::getSystemState ( )

Get the event field value SystemState.

Specifies the current state of the system.

Changes to the ServerState of the system shall trigger a SystemStatusChangeEvent, when the event is supported by the system.

void OpcUa::SystemStatusChangeEventTypeData::getSystemStateValue ( Session pSession,
OpcUa_Variant value 
)
virtual

Get the event field value SystemState 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

Specifies the current state of the system.

Changes to the ServerState of the system shall trigger a SystemStatusChangeEvent, when the event is supported by the system.

void OpcUa::SystemStatusChangeEventTypeData::setSystemState ( OpcUa_ServerState  SystemState)

Set the event field value SystemState.

Specifies the current state of the system.

Changes to the ServerState of the system shall trigger a SystemStatusChangeEvent, when the event is supported by the system.

void OpcUa::SystemStatusChangeEventTypeData::setSystemStateStatus ( OpcUa_StatusCode  status)

Set a status code for the event field value SystemState.

If an event field is not available, a StatusCode must be provided instead of the value to indicate the error situation.
