What occurs when a call event is triggered?

When a call event is triggered, the behavior that runs is related to the mechanisms of synchronous communication within modeling environments. In this context, a call event typically involves sending a request to an operation, and it expects a reply while keeping the calling activity suspended until that reply is received. This means the operation is invoked, and the model awaits a response, reflecting typical synchronous communications in system interactions.

The nature of this mechanism ensures that the subsequent actions are contingent upon the completion of the requested operation, making it crucial for maintaining the integrity and sequence of operations. This interaction allows for precise control of flow in a model, as the triggering of the call event leads to a direct response that influences the further execution of activities within the model.

In contrast, behaviors running asynchronously do not require a reply to proceed, which distinguishes them from the synchronous nature of call events. Also, the triggering of multiple events simultaneously or actions being delayed until a timeout occurs are not characteristics associated with the synchronous behavior of call events, as they are designed to operate in a sequence where immediate feedback is crucial for subsequent processing.
