iox::popo::NotificationInfo🔗

NotificationInfo holds the state of a trigger like the pointer to the triggerOrigin, the notification id and the callback. #include <iceoryx_posh/popo/notification_info.hpp>

Public Functions🔗

Name
NotificationInfo() =default
constructs an empty NotificationInfo
virtual ~NotificationInfo() =default
template <typename T ,typename ContextDataType >
NotificationInfo(T *const notificationOrigin, const uint64_t notificationId, const NotificationCallback< T, ContextDataType > & callback)
constructs a NotificationInfo object
uint64_t getNotificationId() const
returns the notification id
template <typename T >
bool		 doesOriginateFrom(T *const notificationOrigin) const

Public Functions Documentation🔗

function NotificationInfo🔗

NotificationInfo() =default

constructs an empty NotificationInfo

function ~NotificationInfo🔗

virtual ~NotificationInfo() =default

function NotificationInfo🔗

template <typename T ,
typename ContextDataType >
NotificationInfo(
    T *const notificationOrigin,
    const uint64_t notificationId,
    const NotificationCallback< T, ContextDataType > & callback
)

constructs a NotificationInfo object

Parameters:

  • notificationOrigin the origin of the event
  • notificationId id of the event
  • callback the callback of the event

function getNotificationId🔗

uint64_t getNotificationId() const

returns the notification id

Return: the empty NotificationInfo always returns INVALID_ID, otherwise the actual notificationId is returned which can also be INVALID_ID

function doesOriginateFrom🔗

template <typename T >
bool doesOriginateFrom(
    T *const notificationOrigin
) const

confirms the notificationOrigin

Parameters:

  • notificationOrigin the possible notificationOrigin

Return: true if the address is equal to the notificationOrigin, otherwise false. The empty NotificationInfo returns always false.

function getOrigin🔗

template <typename T >
T * getOrigin() const

returns the pointer to the notificationOrigin.

Return: If T equals the Triggerable type it returns the notificationOrigin. Otherwise it calls the errorHandler with a moderate error of kPOPO__EVENT_INFO_TYPE_INCONSISTENCY_IN_GET_ORIGIN and returns nullptr.

function operator()🔗

bool operator()() const

If a callback is set it executes the callback.

Return: true if the callback was called, otherwise false
