The Timer class provides a way to ask for one callback at a time of your choosing, or for regular callbacks at a specified intervals. The default is one callback; calling setRepeating() changes that.
The class provides second resolution, nothing better. Creating a timer with delay/interval of 1 provides the first callback after 1-2 seconds and (if repeating() is true) at 1-second intervals thereafter.
If the system is badly overloaded, callbacks may be skipped. There never is more than one activation pending for a single Timer.
Constructs an timer which will notify owner after delay seconds, or slightly more.
Returns true if this timer will call the EventHandler::execute() function of owner() at some point, and falls if it will not.
In particular, if it is presently calling EventHandler::execute() and will not do it again in the future, so it returns false.
Called by the EventLoop when this Timer should notify its owner().
This function notifies the owner of this Timer's expiration.
Returns a pointer to the the EventHandler object that this Timer will notify.
Returns true if this Timer will notify its owner at regular intervals, and false if it notifies its owner just once. The initial value is false.
Makes this Timer notify its owner at regular intervals if r is true, and just once (more) if r is false.
The initial value is false. If you call setRepeating( false ) on an existing timer, it will be executed once more and then be freed.
Returns the time (as an integer number of seconds increasing towards the future) at which this Timer will call EventHandler::execute(), or 0 if it is not active().
Kills this timer right now, preventing any future callbacks.
