OpcBidirectionalReference Members

Initializes a new instance of the OpcBidirectionalReference class using the targetNode as the target using the type of reference identified by the typeId specified.

C#

public OpcBidirectionalReference(IOpcNode targetNode, OpcNodeId typeId)

Parameters

targetNode IOpcNode

The IOpcNodeInfo in which the reference constructed ceases.

typeId OpcNodeId

The OpcNodeId which identifies the type of reference to represent between the targetNode and its opponent.

Exceptions

ArgumentNullException

The targetNode or typeId is a null reference (Nothing in Visual Basic).

Initializes a new instance of the OpcBidirectionalReference class using the targetNode as the target of the reference and using the value of the type parameter as the type of reference.

C#

public OpcBidirectionalReference(IOpcNode targetNode, OpcReferenceType type)

Parameters

targetNode IOpcNode

The IOpcNodeInfo in which the reference constructed ceases.

type OpcReferenceType

One of the members defined by the OpcReferenceType enumeration to use to setup the type of reference represented.

Exceptions

ArgumentNullException

The targetNode is a null reference (Nothing in Visual Basic).

Initializes a new instance of the OpcBidirectionalReference class using the targetNodeId as the identifier of the target and using the type of reference identified by the typeId specified.

C#

public OpcBidirectionalReference(OpcNodeId targetNodeId, OpcNodeId typeId)

Parameters

targetNodeId OpcNodeId

The OpcNodeId which identifies the node in which the reference constructed ceases.

typeId OpcNodeId

The OpcNodeId which identifies the type of reference to represent between the target identified by the targetNodeId and its opponent.

Exceptions

ArgumentNullException

The targetNodeId or typeId is a null reference (Nothing in Visual Basic).

Initializes a new instance of the OpcBidirectionalReference class using the targetNodeId as the identifier of the target of the reference using the value of the type parameter as the type of the reference.

C#

public OpcBidirectionalReference(OpcNodeId targetNodeId, OpcReferenceType type)

Parameters

targetNodeId OpcNodeId

The OpcNodeId which identifies the node in which the reference constructed ceases.

type OpcReferenceType

One of the members defined by the OpcReferenceType enumeration to use to setup the type of reference represented.

Exceptions

ArgumentNullException

The targetNodeId is a null reference (Nothing in Visual Basic).

Gets the node to which the reference refers to.

C#

public IOpcNode TargetNode { get; }

Property Value

IOpcNode

The IOpcNode to which the reference refers to or a null refernce (Nothing in Visual Basic) in case there this OpcBidirectionalReference has been initialized using a OpcNodeId which identifies the node the reference refers to.

Gets the identifier of the node to which the reference refers to.

C#

public OpcNodeId TargetNodeId { get; }

Property Value

OpcNodeId

The OpcNodeId which identifies the node to which the reference refers to.

Gets a value which defines the pre-defined type of reference represented.

C#

public OpcReferenceType? Type { get; }

Property Value

Nullable<OpcReferenceType>

One of the members defined by the OpcReferenceType enumeration or a null reference (Nothing in Visual Basic) if TypeId refers to a type of reference which is not a built in reference type. The default value is Organizes.

Gets the identifier which identifies the node that defines the semantic of the reference between the source and the target node represented through this OpcBidirectionalReference and generally reflects an operation between the two, such as “A contains B” and vice versa.

C#

public OpcNodeId TypeId { get; }

Property Value

OpcNodeId

The OpcNodeId of the reference type node which defines the relation semantic between the source and the target node. The default value is Organizes.

Retrieves an empty sequence of OpcNodeReference instances.

C#

public IEnumerable<OpcNodeReference> GetReferences()

Returns

IEnumerable<OpcNodeReference>

An empty IEnumerable´1 of OpcNodeReference instances.

Retrieves a sequence with two OpcNodeReference instances using the node specified as the source and target of the references.

C#

public IEnumerable<OpcNodeReference> GetReferences(IOpcNode node)

Parameters

node IOpcNode

The IOpcNode instance from which one OpcNodeReference instance will originate from and in which one will cease.

Returns

IEnumerable<OpcNodeReference>

An IEnumerable´1 of OpcNodeReference instances which contains two instances.

Exceptions

ArgumentNullException

The node is a null reference (Nothing in Visual Basic).

Retrieves a sequence with two OpcNodeReference instances using the nodeId specified as the source and target of the references.

C#

public IEnumerable<OpcNodeReference> GetReferences(OpcNodeId nodeId)

Parameters

nodeId OpcNodeId

The OpcNodeId which identifies the node from which one OpcNodeReference instance will originate from and in which one will cease.

Returns

IEnumerable<OpcNodeReference>

An IEnumerable´1 of OpcNodeReference instances which contains two instances.

Exceptions

ArgumentNullException

The nodeId is a null reference (Nothing in Visual Basic).

Returns a string representing the information contained in the OpcBidirectionalReference.

C#

public override string ToString()

Returns

String

A string which describes the information in this OpcBidirectionalReference.
