Types

type KafkaTrigger

type KafkaTrigger struct {
	// Sensor object
	Sensor *v1alpha1.Sensor
	// Trigger reference
	Trigger *v1alpha1.Trigger
	// Kafka async producer
	Producer sarama.AsyncProducer
	// Logger to log stuff
	Logger *zap.SugaredLogger
}

KafkaTrigger describes the trigger to place messages on Kafka topic using a producer

func NewKafkaTrigger

func NewKafkaTrigger(sensor *v1alpha1.Sensor, trigger *v1alpha1.Trigger, kafkaProducers map[string]sarama.AsyncProducer, logger *zap.SugaredLogger) (*KafkaTrigger, error)

NewKafkaTrigger returns a new kafka trigger context.

func (*KafkaTrigger) ApplyPolicy

func (t *KafkaTrigger) ApplyPolicy(ctx context.Context, resource interface{}) error

ApplyPolicy applies policy on the trigger

func (*KafkaTrigger) ApplyResourceParameters

func (t *KafkaTrigger) ApplyResourceParameters(events map[string]*v1alpha1.Event, resource interface{}) (interface{}, error)

ApplyResourceParameters applies parameters to the trigger resource

func (*KafkaTrigger) Execute

func (t *KafkaTrigger) Execute(ctx context.Context, events map[string]*v1alpha1.Event, resource interface{}) (interface{}, error)

Execute executes the trigger

func (*KafkaTrigger) FetchResource

func (t *KafkaTrigger) FetchResource(ctx context.Context) (interface{}, error)

FetchResource fetches the trigger. As the Kafka trigger is simply a Kafka producer, there is no need to fetch any resource from external source

func (*KafkaTrigger) GetTriggerType

func (t *KafkaTrigger) GetTriggerType() apicommon.TriggerType

GetTriggerType returns the type of the trigger
