is an option for asynchronous operations that specifies functions to apply when events are generated.
- The typical setting for HandlerFunctions is "event1"->f1,"event2"->f2,…, which specifies that when eventi is generated, the function fi should be applied to an association whose elements are specified by HandlerFunctionsKeys.
- The events that can be generated by particular tasks are listed under the functions that submit the tasks.
- In the HandlerFunctions association, the special element "UnhandledEvent"->f uses the function f for any event for which no explicit handler was specified.
