Detailed Description

Wrapper class for the UA stack structure OpcUa_XVType.

This class encapsulates the native OpcUa_XVType structure and handles memory allocation and cleanup for you. UaXVType uses implicit sharing to avoid needless copying and to boost the performance. Only if you modify a shared XVType it creates a copy for that (copy-on-write). So assigning another UaXVType or passing it as parameter needs constant time and is nearly as fast as assigning a pointer.

Constructor & Destructor Documentation

UaXVType::UaXVType ( const UaXVType & other )

Constructs an instance of the class UaXVType with values from another UaXVType object.

Parameters

other the other UaXVType used to initialize the object

UaXVType::UaXVType ( const OpcUa_XVType & other )

Constructs an instance of the class UaXVType with values from another OpcUa_XVType structure.

Parameters

other the other OpcUa_XVType used to initialize the object

UaXVType::UaXVType ( const UaExtensionObject & extensionObject )

Constructs an instance of the class UaXVType initialized with value from a UaExtensionObject.

Parameters

extensionObject the extension object containing the XVType

UaXVType::UaXVType ( const OpcUa_ExtensionObject & extensionObject )

Constructs an instance of the class UaXVType initialized with value from an OpcUa_ExtensionObject structure.

Parameters

extensionObject the extension object containing the XVType

Member Function Documentation

void UaXVType::attach ( OpcUa_XVType * pValue )

Attaches the data of the parameter pValue.

Don't clear the data of pValue afterwards manually, because UaXVType is responsible for it now.

Parameters

[in] pValue Parameter to attach to.

void UaXVType::clear ( )

Clear the data of the UaXVType.

OpcUa_XVType * UaXVType::clone ( const OpcUa_XVType & source )

static

Copy OpcUa_XVType data to a newly allocated OpcUa_XVType.

Parameters

source Source to clone.

Returns: new copy.

void UaXVType::cloneTo	(	const OpcUa_XVType &	source,
		OpcUa_XVType &	copy
	)

static

Copy OpcUa_XVType data to an existing OpcUa_XVType structure.

Parameters

source	the source of the clone operation.
copy	the destination of the clone operation.

OpcUa_XVType * UaXVType::copy ( ) const

Copy UaXVType data to a newly allocated OpcUa_XVType.

Returns: data to a newly allocated OpcUa_XVType.

void UaXVType::copyTo ( OpcUa_XVType * pDst ) const

Copy UaXVType data to an existing OpcUa_XVType structure.

Parameters

pDst	the destination of this copy operation.

OpcUa_XVType * UaXVType::detach ( OpcUa_XVType * pDst )

Detaches the internal XVType structure from this class.

This way you take over the control of releasing the XVType data. If more than one reference exists, the data is copied to pDst instead of being detached.

Returns: If the function succeeds, pDst is returned, otherwise 0 is returned.

Parameters

[out] pDst Pointer to OpcUa_XVType structure that receives the XVType data.

bool UaXVType::operator!= ( const UaXVType & other ) const

Returns true if the other UaXVType is not equal to this.

See Also: operator==

Parameters

other the UaXVType to compare.

Returns: true if other is not equal to this.

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

Assignment operator.

Parameters

other the UaXVType to assign.

Returns: Assignment operator.

bool UaXVType::operator== ( const UaXVType & other ) const

Compare two UaXVType if they are similar.

Parameters

other the UaXVType to compare.

Returns: true if similar, false if not.
