Types

type ScalerBuilder

type ScalerBuilder struct {
	Scaler       scalers.Scaler
	ScalerConfig scalersconfig.ScalerConfig
	Factory      func() (scalers.Scaler, *scalersconfig.ScalerConfig, error)
}

type ScalersCache

type ScalersCache struct {
	ScaledObject             *kedav1alpha1.ScaledObject
	Scalers                  []ScalerBuilder
	ScalableObjectGeneration int64

}

func (*ScalersCache) Close

func (c *ScalersCache) Close(ctx context.Context)

Close closes all scalers in the cache

func (*ScalersCache) GetMetricSpecForScaling

func (c *ScalersCache) GetMetricSpecForScaling(ctx context.Context) []v2.MetricSpec

GetMetricSpecForScaling returns metrics specs for all scalers in the cache

func (*ScalersCache) GetMetricSpecForScalingForScaler

func (c *ScalersCache) GetMetricSpecForScalingForScaler(ctx context.Context, index int) ([]v2.MetricSpec, error)

GetMetricSpecForScalingForScaler returns metrics spec for a scaler identified by the metric name

func (*ScalersCache) GetMetricsAndActivityForScaler

func (c *ScalersCache) GetMetricsAndActivityForScaler(ctx context.Context, index int, metricName string) ([]external_metrics.ExternalMetricValue, bool, time.Duration, error)
