Provides a factory which generates per namespace unique node identifiers as [OpcNodeId](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcnodeid/) instances of the [Numeric](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcnodeidtype/#numeric) type.

## Syntax

<div class="api-signature" data-lang="csharp">

```csharp
public class OpcIncrementalNodeIdFactory : OpcNodeIdFactory
```

</div>

<div class="api-signature" data-lang="vbnet">

```vbnet
Public Class OpcIncrementalNodeIdFactory
    Inherits OpcNodeIdFactory
```

</div>

## Inheritance

[Object](https://learn.microsoft.com/dotnet/api/system.object) → [OpcNodeIdFactory](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcnodeidfactory/) → **OpcIncrementalNodeIdFactory**

## Remarks

The node identifiers are generated using an [uint](https://learn.microsoft.com/dotnet/api/system.uint32). In case there the range of the unsigned integer is exceeded an overflow will be omitted using unchecked increments.
