Detailed Description

template<typename TQueue, typename>
class cms::alpakatools::ScopedContextTask< TQueue, typename >

The aim of this class is to do necessary per-task "initialization" tasks created in ExternalWork acquire():

• setting the current device
• calling edm::WaitingTaskWithArenaHolder::doneWaiting() when necessary and enforce that those get done in a proper way in RAII fashion.
