Description

A configurable one-time job to invoke some special function.

The actual operation is configured as λ-function and the instance manages itself into heap storage and automatically destroys itself after the predetermined invocation. The intended usage is to supply a specifically wired one-time »fire-and-forget« action to the Scheduler as answer so some special processing situation. The front-end handle SpecialJobFun itself is disposable and only serves as builder; even after the front-end is gone, the actual JobFunctor will maintain one self-reference — unless it is invoked...

Warning: obviously this is a dangerous tool; the user must ensure that it is at most invoked once — after that, the instance will self-destroy, leaving a dangling reference.

Todo:: WIP 12/2023 invented to help with Scheduler load testing as part of the »Playback Vertical Slice« — this idea however might be generally useful to handle one-time adjustments from within a play- or planning process.
