func Unslice2(sl interface{}) (one, two export.Aggregator)

Takes a slice of []some.Aggregator and returns a slice of []export.Aggregator

type CheckpointSet struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

CheckpointSet is useful for testing Exporters.

func NewCheckpointSet(resource *resource.Resource) *CheckpointSet

NewCheckpointSet returns a test CheckpointSet that new records could be added. Records are grouped by their encoded labels.

func (p *CheckpointSet) Add(desc *metric.Descriptor, newAgg export.Aggregator, labels ...kv.KeyValue) (agg export.Aggregator, added bool)

Add a new record to a CheckpointSet.

If there is an existing record with the same descriptor and labels, the stored aggregator will be returned and should be merged.

func (p *CheckpointSet) ForEach(_ export.ExportKindSelector, f func(export.Record) error) error

ForEach does not use ExportKindSelected: use a real Processor to test ExportKind functionality.

func (p *CheckpointSet) Reset()

Reset clears the Aggregator state.

type NoopAggregator struct{}

NoopAggregator is useful for testing Exporters.

func (NoopAggregator) Aggregation() aggregation.Aggregation

Aggregation returns an interface for reading the state of this aggregator.

func (NoopAggregator) Kind() aggregation.Kind

Kind implements aggregation.Aggregation.

func (NoopAggregator) Merge(export.Aggregator, *metric.Descriptor) error

Merge implements export.Aggregator.

func (NoopAggregator) SynchronizedMove(export.Aggregator, *metric.Descriptor) error

SynchronizedMove implements export.Aggregator.

func (NoopAggregator) Update(context.Context, metric.Number, *metric.Descriptor) error

Update implements export.Aggregator.
