Functions

func EvalGeneric

func EvalGeneric(obj client.Object, predicates ...predicate.Predicate) bool

EvalGeneric returns true if all predicates match for the given object.

func FromMapper

func FromMapper(mapper Mapper, triggers ...MapperTrigger) predicate.Predicate

FromMapper creates a new predicate from the given Mapper that reacts on the given MapperTriggers.

func HasFinalizer

func HasFinalizer(finalizer string) predicate.Predicate

HasFinalizer returns a predicate that detects if the object has the given finalizer This is used to not requeue all secrets in the cluster (which might be quite a lot), but only requeue secrets from create/update events with the controller's finalizer. This is to ensure, that we properly remove the finalizer in case we missed an important update event for a ManagedResource.

func HasName

func HasName(name string) predicate.Predicate

HasName returns a predicate that matches the given name of a resource.

func HasOperationAnnotation

func HasOperationAnnotation() predicate.Predicate

HasOperationAnnotation is a predicate for the operation annotation.

func IsDeleting

func IsDeleting() predicate.Predicate

IsDeleting is a predicate for objects having a deletion timestamp.

func Not

func Not(p predicate.Predicate) predicate.Predicate

Not inverts the passed predicate.

func ShootIsUnassigned

func ShootIsUnassigned() predicate.Predicate

ShootIsUnassigned is a predicate that returns true if a shoot is not assigned to a seed.

Types

type Mapper

type Mapper interface {
	Map(event event.GenericEvent) bool
}

Mapper maps any event (in form of a GenericEvent) to a boolean whether the event shall be propagated or not.

type MapperFunc

type MapperFunc func(event.GenericEvent) bool

MapperFunc is a function that implements Mapper.

func (MapperFunc) Map

func (f MapperFunc) Map(event event.GenericEvent) bool

Map implements Mapper.

type MapperTrigger

type MapperTrigger uint8

MapperTrigger is a trigger a Mapper can react upon.

const (
	// CreateTrigger is a MapperTrigger for create events.
	CreateTrigger MapperTrigger = iota
	// UpdateOldTrigger is a MapperTrigger for update events with the old meta and object.
	UpdateOldTrigger
	// UpdateNewTrigger is a MapperTrigger for update events with the new meta and object.
	UpdateNewTrigger
	// DeleteTrigger is a MapperTrigger for delete events.
	DeleteTrigger
	// GenericTrigger is a MapperTrigger for generic events.
	GenericTrigger
)
