OpcVariableTypeInfo Class

Namespace: Opc.UaFx
Assemblies: Opc.UaFx.Advanced.dll

Represents type declarations used for variable node types.

C# 

public abstract class OpcVariableTypeInfo : OpcNodeTypeInfo, IOpcType, IOpcNodeTypeInfo, IOpcNodeInfo


Inheritance Object › OpcNodeTypeInfo › OpcVariableTypeInfo


Implements IOpcType, IOpcNodeTypeInfo, IOpcNodeInfo

Properties

Name Description
ArrayDimensions Gets the length for each dimension of an array value of the variable type represented.
ArrayLength Gets the total number of elements in all the dimensions of the array value of the variable type represented.
ArrayRank Gets the rank (number of dimensions) of the array value of the variable type represented. For example, a one-dimensional array returns 1, a two-dimensional array returns 2, and so on.
BaseType Gets the type from which the current OpcNodeTypeInfo directly inherits.
(Inherited from OpcNodeTypeInfo)
Category Gets the NodeCategoryOpcAttribute which identifies the kind of node and is therefore used to classify the node regarding its use and purpose.

DataType
DataTypeId
Documentation Gets any semantic information that would help a human to understand what the type represents.
(Inherited from OpcNodeTypeInfo)
Empty Gets the type to use if their is no specific type data available.
(Inherited from OpcNodeTypeInfo)
IsAbstract (Inherited from OpcNodeTypeInfo)
IsArray Gets a value indicating whether the value of the variable represented is an array.
IsEmpty Gets a value indicating whether the current OpcNodeTypeInfo represents a type to use if there is no specific type described.
(Inherited from OpcNodeTypeInfo)
IsObject Gets a value indicating whether the type is an object node (see Object).
(Inherited from OpcNodeTypeInfo)
IsSystemType Gets a value indicating whether the current IOpcNodeTypeInfo represents one of the predefined built-in node types defined by the OPC UA.
(Inherited from OpcNodeTypeInfo)
IsUnknown Gets a value indicating whether the OpcNodeTypeInfo acts as a placeholder for a referenced type its type declaration could not resolved.
(Inherited from OpcNodeTypeInfo)
IsVariable Gets a value indicating whether the type is an object node (see Variable).
(Inherited from OpcNodeTypeInfo)
Name Gets a value which defines the human-readable name of the type represented. A node which represents this OpcNodeTypeInfo uses the Name as its BrowseName.
(Inherited from OpcNodeTypeInfo)
SymbolicName (Inherited from OpcNodeTypeInfo)
TypeId Gets a value which identifies the type represented. A node which represents this OpcNodeTypeInfo uses the TypeId as its NodeId.
(Inherited from OpcNodeTypeInfo)
TypeSystem Gets the the OpcNodeTypeSystem which conains the node type declaration represented.
(Inherited from OpcNodeTypeInfo)
UnderlyingType Gets the type which provides the implementation of the OpcNodeTypeInfo.
