When a Change Event occurs, what triggers its activation?

The activation of a Change Event is specifically linked to the occurrence of a change in a specified Boolean expression. This means that the Change Event listens for conditions that can be represented as true or false; when the Boolean expression evaluates to a different state (from true to false or vice versa), it triggers the event. This allows for more precise control over when and how events are activated based on specific criteria, making it a valuable construct in modeling behaviors and responses within a system.

Understanding the specifics of how Boolean expressions function helps in systems modeling, as these expressions can encapsulate a wide range of conditions and enable complex decision-making processes. This focus on Boolean expressions as a triggering mechanism allows for cleaner, more explicitly defined rules about what constitutes a change, which in turn supports better modeling practices that adhere to sound principles of system behavior and response.
