GetDataTypeIdsFromModelNodeDescriptors Method (IUADataTypeModelProvider)

Gets data type IDs from given model node descriptors.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<NotNullAttribute()>
Function GetDataTypeIdsFromModelNodeDescriptors( _
   ByVal modelNodeDescriptorList As IReadOnlyList(Of UAModelNodeDescriptor) _
) As ValueResult(Of UAModelNodeDescriptor)()

'Usage
 
Dim instance As IUADataTypeModelProvider
Dim modelNodeDescriptorList As IReadOnlyList(Of UAModelNodeDescriptor)
Dim value() As ValueResult(Of UAModelNodeDescriptor)
 
value = instance.GetDataTypeIdsFromModelNodeDescriptors(modelNodeDescriptorList)

[NotNull()]
ValueResult<UAModelNodeDescriptor>[] GetDataTypeIdsFromModelNodeDescriptors( 
   IReadOnlyList<UAModelNodeDescriptor> modelNodeDescriptorList
)

[NotNull()]
array<ValueResult<UAModelNodeDescriptor^>^>^ GetDataTypeIdsFromModelNodeDescriptors( 
   IReadOnlyList<UAModelNodeDescriptor^>^ modelNodeDescriptorList
)

Parameters

modelNodeDescriptorList

A list of model node descriptors.

The value of this parameter cannot be null (Nothing in Visual Basic).

The individual elements of the parameter value cannot be null (Nothing in Visual Basic).

Return Value

An array of value results with the data type IDs obtained, for corresponding indexes of the input list.

This method never returns null (Nothing in Visual Basic).

The individual elements of the returned value are never null (Nothing in Visual Basic).

Remarks

You can obtain the data type model provider interface (IUADataTypeModelProvider) from the OpcLabs.EasyOpc.UA.Plugins.ComplexData.IEasyUAClientComplexData.DataTypeModelProvider property of the OpcLabs.EasyOpc.UA.Plugins.ComplexData.IEasyUAClientComplexData service.

This is a multiple-operation method. In a properly written program, it does not throw any exceptions. You should therefore not put try/catch statements or similar constructs around calls to this method. The only exceptions thrown by this method are for usage errors, i.e. when your code violates the usage contract of the method, such as passing in invalid arguments or calling the method when the state of the object does not allow it. Any operation-related errors (i.e. errors that depend on external conditions that your code cannot reliably check) are indicated in the result objects returned by the method. For more information, see Multiple-operation Methods and Do not catch any exceptions with asynchronous or multiple-operation methods.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
