Create an empty labelDefinitionCreatorMultiSensor object.

ldc = labelDefinitionCreatorMultiSensor;

Add a label with the name "TrafficLight". Specify the type of label as "Rectangle". Adding a "Rectangle" also adds a "Cuboid" entry to the label definitions table.

addLabel(ldc,"TrafficLight","Rectangle")

Add attribute "Active" to the label. Specify the attribute type as "Logical" with the value true.

addAttribute(ldc,"TrafficLight","Active","Logical",true)

Display information about the attributes under the label "TrafficLight" using the object function info.

info(ldc,"TrafficLight")
           Name: "TrafficLight"
     SignalType: Image
      LabelType: Rectangle
          Group: "None"
     LabelColor: {''}
     Attributes: "Active"
