class SignalObserver

Defined at line 22 of file ../../zircon/kernel/object/include/object/signal_observer.h

SignalObserver implementations may register to be called when

a signal becomes active on a particular Dispatcher.

Implementations must be thread compatible, but need not be thread safe.

Public Methods

void OnMatch (zx_signals_t signals, OwnedWaitQueue * queue_to_own)

Called when the set of active signals matches an expected set.

At the time this is call, it is safe to delete this object: the

caller will not interact with it again.

WARNING: This is called under Dispatcher's lock

void OnCancel (zx_signals_t signals)

Called when the registered handle (which refers to a handle to the

Dispatcher object) is being destroyed/"closed"/transferred. (The

object itself may also be destroyed shortly afterwards.)

At the time this is call, it is safe to delete this object: the

caller will not interact with it again.

WARNING: This is called under Dispatcher's lock
