Properties
TargetNode
Gets the node to which the reference refers to.
public IOpcNode TargetNode { get; }Public ReadOnly Property TargetNode As IOpcNodeProperty value
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.
TargetNodeId
Gets the identifier of the node to which the reference refers to.
public OpcNodeId TargetNodeId { get; }Public ReadOnly Property TargetNodeId As OpcNodeIdProperty value
The OpcNodeId which identifies the node to which the reference refers to.
Type
Gets a value which defines the pre-defined type of reference represented.
public OpcReferenceType? Type { get; }Public ReadOnly Property Type As OpcReferenceType?Property value
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.
TypeId
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.
public OpcNodeId TypeId { get; }Public ReadOnly Property TypeId As OpcNodeIdProperty value
The OpcNodeId of the reference type node which defines the relation semantic between the source and the target node. The default value is Organizes.
