Detailed Description

OPC UA ElementOperand used in ContentFilterElement.

This class is used to build and hold an OPC UA ElementOperand used in the UaContentFilterElement. This class is concrete implementation of the abstract UaFilterOperand. It contains a content filter element. This type is used to build a logic tree of subelements by linking the operand of one element to a sub-element

Constructor & Destructor Documentation

UaElementOperand::UaElementOperand

(

)

Constructs an empty element filter operand object.

UaElementOperand::~UaElementOperand

(

)

[virtual]

Destroys the element filter operand object

Member Function Documentation

UaFilterOperand::FilterOperandType UaElementOperand::getFilterOperandType

(

)

const [virtual]

Returns the filter operand type Element.

Implements UaFilterOperand.

OpcUa_UInt32 UaElementOperand::index

(

)

const

Returns the index of the element operand.

UaContentFilterElement * UaElementOperand::pContentFilterElement

(

)

const

Returns the contained content filter elment (Server use only).

This method is used only in the server implementation to build a logical tree

void UaElementOperand::setContentFilterElement

(

UaContentFilterElement *

pElement )

Sets the content filter element. The passed element will be deleted by the UaElementOperand (Server use only).

This method is used only in the server implementation to build a logical tree

Parameters:

[in]

pElement

The element itself

UaStatus UaElementOperand::setContentFilterElement	(	UaContentFilter *	pUaContentFilter,
		OpcUa_UInt32	noOfElements,
		const OpcUa_ContentFilterElement *	pElements,
		OpcUa_UInt32	elementIndex,
		OpcUa_EventFilterResult *	pEventFilterResult,
		OpcUa_Boolean &	hasFilterError
	)

Sets the content filter element (Server use only).

This method is used only in the server implementation to build a logical tree

Returns:

Status code

Parameters:

[in]	pUaContentFilter	A pointer set to the filter
[in]	noOfElements	The number of elements.
[in]	pElements	The elements itself
[in]	elementIndex	The index of the given element
[in,out]	pEventFilterResult	The result of the filter operation
[in,out]	hasFilterError	Indicates if there are errors occured in the filter operation.

void UaElementOperand::setIndex

(

OpcUa_UInt32

index )

Sets the index of the element operand.

Parameters:

[in]

index

the index of the element operant
