Physicalize Method (_UADataSetWriterDescriptor)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.PubSub.ComTypes Namespace > _UADataSetWriterDescriptor Interface : Physicalize Method
The URI string of the PubSub transport profile.
Determines whether the (standard) topic tree is used.
When true, the physicalization is performed even when the descriptor requires resolution.
Physicalizes the PubSub object descriptor, by removing the logical information from it.
Syntax
'Declaration
 
Sub Physicalize( _
   ByVal transportProfileUriString As String, _
   ByVal assumeTopicTree As Boolean, _
   ByVal force As Boolean _
) 
'Usage
 
Dim instance As _UADataSetWriterDescriptor
Dim transportProfileUriString As String
Dim assumeTopicTree As Boolean
Dim force As Boolean
 
instance.Physicalize(transportProfileUriString, assumeTopicTree, force)

Parameters

transportProfileUriString
The URI string of the PubSub transport profile.
assumeTopicTree
Determines whether the (standard) topic tree is used.
force
When true, the physicalization is performed even when the descriptor requires resolution.
Exceptions
ExceptionDescription

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

A method call was invalid for the object's current state.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

When force is false, it is only allowed to call this method on descriptors that do not require resolution. That is, the descriptor must already contain enough physical information for it to be usable. The physicalization then just removes the associated logical information that is not necessary in this descriptor.

Requirements

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