Member Function Documentation
Tasking::ExecutableItem ExecutableItem::withLog(const QString &logName) const
Attaches a custom debug printout to a copy of this ExecutableItem, issued on task startup and after the task is finished, and returns the coupled item.
The debug printout includes a timestamp of the event (start or finish) and logName to identify the specific task in the debug log.
The finish printout contains the additional information whether the execution was synchronous or asynchronous, its result (the value described by the DoneWith enum), and the total execution time in milliseconds.
Tasking::ExecutableItem ExecutableItem::withTimeout(std::chrono::milliseconds timeout, const std::function<void ()> &handler = {}) const
Attaches TimeoutTask to a copy of this ExecutableItem, elapsing after timeout in milliseconds, with an optionally provided timeout handler, and returns the coupled item.
When the ExecutableItem finishes before timeout passes, the returned item finishes immediately with the task's result. Otherwise, handler is invoked (if provided), the task is canceled, and the returned item finishes with an error.
