Class AggregationData

java.lang.Object

io.opencensus.stats.AggregationData

Direct Known Subclasses:

AggregationData.CountData, AggregationData.DistributionData, AggregationData.LastValueDataDouble, AggregationData.LastValueDataLong, AggregationData.MeanData, AggregationData.SumDataDouble, AggregationData.SumDataLong

@Immutable
public abstract class AggregationData
extends Object

AggregationData is the result of applying a given Aggregation to a set of MeasureValues.

AggregationData currently supports 6 types of basic aggregation values:

• SumDataDouble
• SumDataLong
• CountData
• DistributionData
• LastValueDataDouble
• LastValueDataLong

ViewData will contain one AggregationData, corresponding to its Aggregation definition in View.
