Interface Summary

Interface	Description
Consolidator	Consolidates a set of measurements collected at a smaller step size to a set a measurement at a larger step size that is an even multiple of the primary.
DataExpr	Data expressions for defining how to aggregate values.
DataExpr.AggregateFunction	Base type for simple aggregate functions.
DataExpr.Aggregator	Helper for incrementally computing an aggregate of a set of tag values.
DataExpr.SimpleAggregator	Base type for simple aggregators that have a single result value.
EvaluatorConfig	Additional interface that can be implemented by the AtlasConfig instance providing knobs for internal registry details.
Query	Query for matching based on tags.
Query.KeyQuery	Base interface for simple queries that check the value associated with a single key.
QueryIndex.CacheSupplier<V>	Supplier to create a new instance of a cache used for other checks.

Class Summary

Consolidator.Max	Selects the maximum value that is reported.
Consolidator.None	Placeholder implementation used when the primary and consolidated step sizes are the same.
DataExpr.All	Includes all datapoints that match the query expression.
DataExpr.Count	Aggregates all datapoints that match the query to a single datapoint that is the number of input values.

DataExpr.GroupBy	Compute a set of time series matching the query and grouped by the specified keys.
DataExpr.KeepRollup	Rollup inputs by only keeping the specified keys.
DataExpr.Max	Aggregates all datapoints that match the query to a single datapoint that is the maximum of the input values.
DataExpr.Min	Aggregates all datapoints that match the query to a single datapoint that is the minimum of the input values.
