Constructor & Destructor Documentation

Alarm() [1/4]

grpc::Alarm::Alarm

(

)

Create an unset completion queue alarm.

~Alarm()

grpc::Alarm::~Alarm ( )

override

Destroy the given completion queue alarm, cancelling it in the process.

Alarm() [2/4]

template<typename T >

grpc::Alarm::Alarm ( grpc::CompletionQueue *  cq, const T &  deadline, void *  tag  )

inline

DEPRECATED: Create and set a completion queue alarm instance associated to cq.

This form is deprecated because it is inherently racy.

Alarm() [3/4]

grpc::Alarm::Alarm ( const Alarm &  )

delete

Alarms aren't copyable.

Alarm() [4/4]

grpc::Alarm::Alarm ( Alarm &&  rhs )

inlinenoexcept

Alarms are movable.

Member Function Documentation

Cancel()

void grpc::Alarm::Cancel

(

)

Cancel a completion queue alarm.

Calling this function over an alarm that has already fired has no effect.

operator=() [1/2]

Alarm& grpc::Alarm::operator= ( Alarm &&  rhs )

inlinenoexcept

operator=() [2/2]

Alarm& grpc::Alarm::operator= ( const Alarm &  )

delete

Set() [1/2]

template<typename T >

void grpc::Alarm::Set ( const T &  deadline, std::function< void(bool)>  f  )

inline

Set an alarm to invoke callback f.

The argument to the callback states whether the alarm expired at deadline (true) or was cancelled (false)

Set() [2/2]

template<typename T >

void grpc::Alarm::Set ( grpc::CompletionQueue *  cq, const T &  deadline, void *  tag  )

inline

Trigger an alarm instance on completion queue cq at the specified time.

Once the alarm expires (at deadline) or it's cancelled (see Cancel), an event with tag tag will be added to cq. If the alarm expired, the event's success bit will be true, false otherwise (ie, upon cancellation).
