presetTaskAsFailed()

void edm::WaitingTaskHolder::presetTaskAsFailed ( std::exception_ptr  iExcept )

inline

Use in the case where you need to inform the parent task of a failure before some other child task which may be run later reports a different, but related failure. You must later call doneWaiting in the same thread passing the same exceptoin.
