## Properties

### Children

Gets a collection of [OpcAddInstanceNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcaddinstancenode/) instances which define the sub-ordinated nodes to add as children to the node to add.

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

```csharp
public OpcAddNodeCollection Children { get; }
```

</div>

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

```vbnet
Public ReadOnly Property Children As OpcAddNodeCollection
```

</div>

**Property value**

[OpcAddNodeCollection](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcaddnodecollection/)

An instance of the [OpcAddNodeCollection](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcaddnodecollection/) class with the [OpcAddInstanceNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcaddinstancenode/) instances to process after the node defined by this [OpcAddObjectTypeNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcaddobjecttypenode/) has been added.

### IsAbstract

<span class="api-meta">override</span>

Gets or sets a value indicating whether the object type node to add is abstract and must be overridden.

```csharp
public override bool IsAbstract { get; set; }
```

</div>

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

```vbnet
Public Overrides Property IsAbstract As Boolean
```

</div>

**Property value**

[Boolean](https://learn.microsoft.com/dotnet/api/system.boolean)

The value true if the object type node to add is abstract; otherwise the value false (the default value).

**Overrides**

[IsAbstract](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcaddtypenode/members#isabstract)
