public class FunctionTask
extends Task
                    
```
A specialized Task for modeling serverless functions and function-as-a-service (FaaS) systems. FunctionTask extends the basic Task with additional properties for modeling cold start delays (setupTime) and teardown delays (delayOffTime) that are characteristic of serverless computing environments.
