Instantiation

The following node classes can be created in the Nodeset Editor: UA_Object, UA_Variable and UA_Method. The editor supports the instantiation of UA_DataType nodes and UA_ObjectType nodes for this purpose. Typical instantiation scenarios are described in more detail below:

Create a folder:

As instances of the ObjectType "FolderType" are often used to structure the namespace, it is possible to add this directly under the clicked node via the context menu. Alternatively, the specified keyboard shortcut can be used if a node is chosen in the Instance Explorer:

Creating a variable or an object

Creating new variable or object instances is usually done by a drag and drop operation from a data type or object type on the Type Explorer. Navigate to the desired data type in the Type Explorer and drag and drop it onto a node in the Instance Explorer. As a result, a corresponding instance of this data type is created there. In our example, we use the Boolean data type.

UA_ObjectType nodes with their entire hierarchy can also be created as instances according to the same scheme.
