**Important**  
This data type is a UNION, so only one of the following members can be specified when used or returned.

 ** actuator **   <a name="iotfleetwise-Type-Node-actuator"></a>
Information about a node specified as an actuator.  
An actuator is a digital representation of a vehicle device.
Type: [Actuator](API_Actuator.md) object  
Required: No

 ** attribute **   <a name="iotfleetwise-Type-Node-attribute"></a>
Information about a node specified as an attribute.  
An attribute represents static information about a vehicle.
Type: [Attribute](API_Attribute.md) object  
Required: No

 ** branch **   <a name="iotfleetwise-Type-Node-branch"></a>
Information about a node specified as a branch.  
A group of signals that are defined in a hierarchical structure.
Type: [Branch](API_Branch.md) object  
Required: No

 ** property **   <a name="iotfleetwise-Type-Node-property"></a>
Represents a member of the complex data structure. The `datatype` of the property can be either primitive or another `struct`.  
Type: [CustomProperty](API_CustomProperty.md) object
