Interface InternalEvent

pkg/apiserver/storage/interfaces.go:38–47

InternalEvent is an internal event that can be converted to *watch.Event based on watcher's Selectors. For example, an internal event may be converted to an ADDED event for one watcher, and to a MODIFIED event for another.

// For example, an internal event may be converted to an ADDED event for one watcher, and to a MODIFIED event
// for another.
type InternalEvent interface {
	// ToWatchEvent converts the InternalEvent to *watch.Event based on the provided Selectors.
	// It will be called once for all watchers that are interested in the event. Expensive computation that will repeat
	// for all watchers should be placed in GenEventFunc as pre-process. For example, the routine that groups a list of
	// pods by nodes is a potential candidate.
	ToWatchEvent(selectors *Selectors, isInitEvent bool) *watch.Event
	// GetResourceVersion returns the resourceVersion of this event.
	// The resourceVersion is used to filter out previously buffered events when watcher is started.
	GetResourceVersion() uint64
}

// GenEventFunc generates InternalEvent from the add/update/delete of an object.
// Only a single InternalEvent will be generated for each add/update/delete, and the InternalEvent itself should be
