FlagDispatcher

class FlagDispatcher extends EventDispatcherBasevoid

Dispatches a SubscribableFlagEvent.

Subscribers are notified only when the flag is set. Subsequent calls to raise don't trigger anything. Any handlers added while the flag is raised are immediately invoked.

Resetting the flag doesn't notify the subscribers, but raising it again does.
