friend class observer_proxy
task_scheduler_observer(task_arena &a)
Construct local observer for a given arena in inactive state (observation disabled).
void __TBB_EXPORTED_METHOD observe(bool state=true)
Enable or disable observation.
friend class internal::observer_proxy
friend class observer_list
task_scheduler_observer_v3()
Construct observer with observation disabled.
friend class internal::observer_list
intptr_t my_context_tag
contains task_arena pointer or tag indicating local or global semantics of the observer
atomic< intptr_t > my_busy_count
Counter preventing the observer from being destroyed while in use by the scheduler.
virtual void on_scheduler_exit(bool)
Exit notification.
virtual void on_scheduler_entry(bool)
Entry notification.
static const intptr_t v6_trait
#define __TBB_EXPORTED_METHOD
virtual ~task_scheduler_observer()
observer_proxy * my_proxy
Pointer to the proxy holding this observer.
void observe(bool state=true)
Enable or disable observation.
#define __TBB_ASSERT_EX(predicate, comment)
"Extended" version is useful to suppress warnings if a variable is only used with an assert
task_scheduler_observer(bool local=false)
Construct local or global observer in inactive state (observation disabled).
bool is_observing() const
Returns true if observation is enabled, false otherwise.
virtual ~task_scheduler_observer_v3()
Destructor automatically switches observation off if it is enabled.
