createAccumulation

createAccumulation(): undefined

Implementation of Aggregator.createAccumulation
- Defined in packages/sdk-metrics/src/aggregator/Drop.ts:27
Create a clean state of accumulation.

Returns undefined

diff

diff(_previous: undefined, _current: undefined): undefined

Implementation of Aggregator.diff
- Defined in packages/sdk-metrics/src/aggregator/Drop.ts:35
Returns a new DELTA aggregation by comparing two cumulative measurements.

Parameters
- _previous: undefined
- _current: undefined

- _delta: undefined
Returns undefined

toMetricData

toMetricData(_descriptor: MetricDescriptor, _aggregationTemporality: AggregationTemporality, _accumulationByAttributes: AccumulationRecord<undefined>[], _endTime: HrTime): Maybe<MetricData>

Implementation of Aggregator.toMetricData
- Defined in packages/sdk-metrics/src/aggregator/Drop.ts:39
Returns the MetricData that this Aggregator will produce.

Parameters
- _descriptor: MetricDescriptor
- _aggregationTemporality: AggregationTemporality
- _accumulationByAttributes: AccumulationRecord<undefined>[]
- _endTime: HrTime
