ndn::util::NotificationSubscriberBase::NotificationSubscriberBase ( Face &  face, const Name &  prefix, time::milliseconds  interestLifetime  )

protected

construct a NotificationSubscriber

Note

The subscriber is not started after construction. User should add one or more handlers to onNotification, and invoke .start().

getInterestLifetime()

time::milliseconds ndn::util::NotificationSubscriberBase::getInterestLifetime ( ) const

inline

Returns

InterestLifetime of Interests to retrieve notifications

This must be greater than FreshnessPeriod of Notification Data packets, to ensure correct operation of this subscriber implementation.

Definition at line 52 of file notification-subscriber.hpp.

isRunning()

bool ndn::util::NotificationSubscriberBase::isRunning ( ) const

inline

Definition at line 58 of file notification-subscriber.hpp.

start()

void ndn::util::NotificationSubscriberBase::start

(

)

start or resume receiving notifications
