Detailed Description

This class handles status codes, conversions of the status code and diagnostic information.

The class is derived from UaStatusCode and is used to combine the StatusCode with associated diagnostic information in one object. The class UaStatusCode encapsulated OPC UA data type StatusCodes and conversions from and to Classic OPC codes

See UaStatusCode for StatusCode related documentation and functions.

Constructor & Destructor Documentation

UaStatus::UaStatus ( const OpcUa_StatusCode & other )

Constructs a status with empty diagnostic info and the passed status code.

Parameters

other the status code as OpcUa_StatusCode.

UaStatus::UaStatus ( const UaStatusCode & other )

Constructs a status with empty diagnostic info and the passed status code.

Parameters

other the status code as UaStatusCode.

UaStatus::UaStatus ( const UaStatus & other )

Constructs a status with another UaStatus.

Parameters

other the other status as UaStatus.

Member Function Documentation

UaStatus & UaStatus::operator= ( const OpcUa_StatusCode & other )

Assigns other status code to this status, resets the diagnostic information and returns a reference to this status.

Parameters

other the status code to assign as OpcUa_StatusCode

Returns: The reference to the changes status

UaStatus & UaStatus::operator= ( const UaStatusCode & other )

Assigns other status code to this status, resets the diagnostic information and returns a reference to this status.

Parameters

other the status code to assign as UaStatusCode

Returns: The reference to the changes status

UaStatus & UaStatus::operator= ( const UaStatus & other )

Assigns other status to this status and returns a reference to this status.

Parameters

other the other UaStatus to assign.

Returns: The reference to the changes status

UaDiagnosticInfo* UaStatus::pDiagnosticInfo ( ) const

inline

Provides access to the optional DiagnosticInformation.

The returned pointer is NULL if there is no DiagnosticInformation available.

void UaStatus::setAdditionalInfo ( const UaString & sAdditionalInfo )

Set the string for additional vendor specific diagnostic information.

Parameters

sAdditionalInfo the additional diagnostic information.

void UaStatus::setDiagnosticInfo	(	const UaString &	namespaceUri,
		const UaString &	symbolicId,
		const UaLocalizedText &	localizedText
	)

Set a symbolicId and a diagnostic info string used to provide diagnostic information.

Parameters

namespaceUri	The namespace URI used together with the SymbolicId.
symbolicId	The symbolic Id as string. A vendor-specific symbolic identifier string identifies an error or condition. The maximum length of this string is 32 characters. Servers wishing to return a numeric return code should convert the return code into a string and return the string in this identifier. The UaStatus class provides another overloaded member to pass a numeric code.
localizedText	An optional vendor-specific localized text string describing the error condition related to the symbolic id. The maximum length of this text string is 256 characters.

void UaStatus::setDiagnosticInfo	(	const UaString &	namespaceUri,
		OpcUa_UInt32	numericReturnCode,
		const UaLocalizedText &	localizedText
	)

Set a numeric return code and a diagnostic info.

Parameters

namespaceUri	The namespace URI used together with the numericReturnCode to compose the SymbolicId.
numericReturnCode	A numeric return code that gets converted into a string used as SymbolicId in the diagnostic information.
localizedText	An optional vendor-specific localized text string describing the error condition related to the numeric code. The maximum length of this text string is 256 characters..

void UaStatus::setDiagnosticInfo ( UaDiagnosticInfo * pDiagnosticInfo )

Set a UaDiagnosticInfo object.

The UaStatus object takes over the reference of the caller. If the caller did not create the UaDiagnosticInfo object, the caller must increment the reference count of the UaDiagnosticInfo object with addRef() before calling this function.

Parameters

pDiagnosticInfo The UaDiagnosticInfo object to set.

void UaStatus::setInnerStatus ( const UaStatus & innerStatus )

Set the nested inner status containing a StatusCode and optional inner DiagnosticInformation.

Parameters

innerStatus the inner status.

void UaStatus::setStatus	(	OpcUa_StatusCode	statusCode,
		const UaString &	sDiagnosticInfo
	)

Set a status code and a diagnostic info.

Parameters

statusCode	the OPC UA Status code
sDiagnosticInfo	An optional vendor-specific localized text string describing the error condition. The maximum length of this text string is 256 characters..
