observe()

void __TBB_EXPORTED_METHOD tbb::internal::task_scheduler_observer_v3::observe

(

bool

state = true

)

Enable or disable observation.

For local observers the method can be used only when the current thread has the task scheduler initialized or is attached to an arena.

Repeated calls with the same state are no-ops.

on_scheduler_entry()

virtual void tbb::internal::task_scheduler_observer_v3::on_scheduler_entry ( bool  )

inlinevirtual

Entry notification.

Invoked from inside observe(true) call and whenever a worker enters the arena this observer is associated with. If a thread is already in the arena when the observer is activated, the entry notification is called before it executes the first stolen task.

Obsolete semantics. For global observers it is called by a thread before the first steal since observation became enabled.

on_scheduler_exit()

virtual void tbb::internal::task_scheduler_observer_v3::on_scheduler_exit ( bool  )

inlinevirtual

Exit notification.

Invoked from inside observe(false) call and whenever a worker leaves the arena this observer is associated with.

Obsolete semantics. For global observers it is called by a thread before the first steal since observation became enabled.
