Member Function Documentation

activation()

activity::Proc activation ( Activity &  thisHook, Time  now, void *  executionCtx  )

inlineoverrideprivatevirtual

Callback on activation of the corresponding HOOK-Activity.

Parameters

thisHook	the Activity record wired to this hook
now	current »wall-clock-time« as used by the Scheduler
executionCtx	opaque pointer to the actual execution context

Returns

decision how to proceed with the activation

Remarks

the intended use is to rig this callback based on additional knowledge regarding the usage context. Through thisHook, the follow-up chain is accessible, and an additional payload data field (size_t). Since the execution context is a concept, it is necessary to know the actual type of the concrete execution context and cast down in the implementation. This mechanism is used especially for detecting expected test invocations.

Implements Hook.
