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 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 Or

func Or(predicates ...predicate.Predicate) predicate.Predicate

Or returns a composite predicate that implements a logical OR of the predicates passed to it. TODO: This is a copy of "sigs.k8s.io/controller-runtime/pkg/predicate.Or" with the addition of the InjectFunc.

Delete this code once the upstream library supports the InjectFunc as well.

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
)
