type NotificationController

type NotificationController interface {
	Run(threadiness int, stopCh <-chan struct{})
}

type NotificationDelivery

type NotificationDelivery struct {
	// Trigger is the trigger of the notification delivery
	Trigger string
	// Destination is the destination of the notification delivery
	Destination services.Destination
	// AlreadyNotified indicates that this notification was already delivered in a previous iteration
	AlreadyNotified bool
}

NotificationDelivery represents a notification that was delivered

type NotificationEventSequence

type NotificationEventSequence struct {
	// Key is the resource key. Format is the namespaced name
	Key string

	Delivered []NotificationDelivery
	// Errors is a list of errors that occurred during the processing iteration
	Errors []error
	// Warnings is a list of warnings that occurred during the processing iteration
	Warnings []error
}

NotificationEventSequence represents a sequence of events that occurred while processing an object for notifications
