40 * The TriggerEvent class is used to send events between threads. For example, this can be used
41 * to wake up one thread from another thread.
43 * Typically, these should be created in the application thread.
45 * The observer will be informed whenever the event is triggered.
47 * The implementation of TriggerEvent uses an event file descriptor.
49 class TriggerEvent : public TriggerEventInterface
55 * Creates an event file descriptor and starts a GSource which reads from the file
56 * descriptor when there is data.
58 * @param[in] callback The callback to call
59 * @param[in] options Trigger event options.
60 * @note The ownership of callback is taken by this class.
62 TriggerEvent( CallbackBase* callback, TriggerEventInterface::Options options = TriggerEventInterface::NONE );
74 * This can be called from one thread in order to wake up another thread.
81 * Called when our event file descriptor has been written to.
