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 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 HasPurpose

func HasPurpose(purpose extensionsv1alpha1.Purpose) predicate.Predicate

HasPurpose filters the incoming Controlplanes for the given spec.purpose

func HasType

func HasType(typeName string) predicate.Predicate

func IsDeleting

func IsDeleting() predicate.Predicate

IsDeleting is a predicate for objects having a deletion timestamp.

func LastOperationNotSuccessful

func LastOperationNotSuccessful() predicate.Predicate

LastOperationNotSuccessful is a predicate for unsuccessful last operations for creation events.

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
)
