Modifier and Type	Method	Description
static boolean	TopNQueryEngine.canApplyExtractionInPost(TopNQuery query)	ExtractionFn which are one to one may have their execution deferred until as late as possible, since which value is used as the grouping key itself doesn't particularly matter.
TopNQueryBuilder	TopNQueryBuilder.copy(TopNQuery query)	Deprecated.
void	DefaultTopNQueryMetrics.dimension(TopNQuery query)
void	TopNQueryMetrics.dimension(TopNQuery query)	Sets getDimensionSpec().getDimension() of the given query as dimension.
CacheStrategy<Result<TopNResultValue>,Object,TopNQuery>	TopNQueryQueryToolChest.getCacheStrategy(TopNQuery query)
void	DefaultTopNQueryMetrics.granularity(TopNQuery query)
void	TopNQueryMetrics.granularity(TopNQuery query)	Sets the granularity of BaseQuery.getGranularity() of the given query as dimension.
TopNQueryMetrics	TopNQueryQueryToolChest.makeMetrics(TopNQuery query)
com.google.common.base.Function<Result<TopNResultValue>,Result<TopNResultValue>>	TopNQueryQueryToolChest.makePostComputeManipulatorFn(TopNQuery query, MetricManipulationFn fn)
com.google.common.base.Function<Result<TopNResultValue>,Result<TopNResultValue>>	TopNQueryQueryToolChest.makePreComputeManipulatorFn(TopNQuery query, MetricManipulationFn fn)
static TopNResultBuilder	BaseTopNAlgorithm.makeResultBuilder(TopNParams params, TopNQuery query)
void	DefaultTopNQueryMetrics.numComplexMetrics(TopNQuery query)

void	DefaultTopNQueryMetrics.numMetrics(TopNQuery query)
void	TopNQueryMetrics.numMetrics(TopNQuery query)	Sets the number of metrics of the given topN query as dimension.
void	DefaultTopNQueryMetrics.query(TopNQuery query)
Sequence<Result<TopNResultValue>>	TopNQueryEngine.query(TopNQuery query, StorageAdapter adapter, TopNQueryMetrics queryMetrics)	Do the thing - process a StorageAdapter into a Sequence of TopNResultValue, with one of the fine TopNAlgorithm available chosen based on the type of column being aggregated.
RowSignature	TopNQueryQueryToolChest.resultArraySignature(TopNQuery query)
Sequence<Object[]>	TopNQueryQueryToolChest.resultsAsArrays(TopNQuery query, Sequence<Result<TopNResultValue>> resultSequence)
Optional<Sequence<FrameSignaturePair>>	TopNQueryQueryToolChest.resultsAsFrames(TopNQuery query, Sequence<Result<TopNResultValue>> resultSequence, MemoryAllocatorFactory memoryAllocatorFactory, boolean useNestedForUnknownTypes)	This returns a single frame containing the rows of the topN query's results
void	DefaultTopNQueryMetrics.threshold(TopNQuery query)
void	TopNQueryMetrics.threshold(TopNQuery query)	Sets getThreshold() of the given query as dimension.
