CreateByte Method

Creates a publisher Id with given byte identifier.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<NotNullAttribute()>
<PureAttribute()>
Public Shared Function CreateByte( _
   ByVal byteIdentifier As Byte _
) As UAPublisherId

'Usage
 
Dim byteIdentifier As Byte
Dim value As UAPublisherId
 
value = UAPublisherId.CreateByte(byteIdentifier)

[NotNull()]
[Pure()]
public static UAPublisherId CreateByte( 
   byte byteIdentifier
)

[NotNull()]
[Pure()]
public:
static UAPublisherId^ CreateByte( 
   byte byteIdentifier
)

Parameters

byteIdentifier: A byte identifier of the publisher Id.

Return Value

Returns a byte publisher Id with the specified identifier.

Because the UASubscribeDataSetFilter has an implicit conversion from UAPublisherId, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned UAPublisherId (containing the publisher Id that you want to allow in the filter) in any place where UASubscribeDataSetFilter is expected as input, and the corresponding OPC UA subscribe dataset filter will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UASubscribeDataSetFilter.FromUAPublisherId static method instead.

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

Remarks

It is intentional that there is no way to directly construct a numerical UAPublisherId without having to somehow explicitly state the desired type. This design attempts to prevent unwanted creation of publisher Ids with wrong type.

This method is pure, i.e. it does not have observable side effects.

Requirements

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