Control Accessors

Control accessors perform side effects on other attributes when they are evaluated. They represent the control structures and instructions of a programming language. In the Group Inspector, you can view them from the “Behaviors” and “Interaction” notebook pages, under the “do” clause attached to each attribute.

These accessors are write-only. They do not record the last value tested. If you only define a Control accessor for a value, you will not be able to read this value back. To store the value associated with an accessor, you must define a Value accessor with the same name.

The different Control accessors are described as follows:

• Assign

• Condition

• Format

• Increment

• Min/Max

• Multiple

• Notify

• Script

• Switch

• Toggle
