Types

type Aggregator

type Aggregator struct {
	// contains filtered or unexported fields
}

func New

func New() *Aggregator

New returns a new measure aggregator for computing max, sum, and count.

func (*Aggregator) Collect

func (c *Aggregator) Collect(ctx context.Context, rec export.MetricRecord, exp export.MetricBatcher)

Collect checkpoints the current value (atomically) and exports it.

func (*Aggregator) Count

func (c *Aggregator) Count() int64

Count returns the accumulated count.

func (*Aggregator) Max

func (c *Aggregator) Max() core.Number

Max returns the accumulated max as a Number.

func (*Aggregator) Merge

func (c *Aggregator) Merge(oa export.MetricAggregator, desc *export.Descriptor)

func (*Aggregator) Sum

func (c *Aggregator) Sum() core.Number

Sum returns the accumulated sum as a Number.

func (*Aggregator) Update

func (c *Aggregator) Update(_ context.Context, number core.Number, rec export.MetricRecord)

Update modifies the current value (atomically) for later export.
