withQuerySegmentSpec

public TimeseriesQuery withQuerySegmentSpec(QuerySegmentSpec querySegmentSpec)

Description copied from interface: Query

Returns a new query, identical to this one, but with a different associated QuerySegmentSpec. This often changes the behavior of Query.getRunner(QuerySegmentWalker), since most queries inherit that method from BaseQuery, which implements it by calling QuerySegmentSpec.lookup(org.apache.druid.query.Query<T>, org.apache.druid.query.QuerySegmentWalker).

withDataSource

public Query<Result<TimeseriesResultValue>> withDataSource(DataSource dataSource)

optimizeForSegment

public Query<Result<TimeseriesResultValue>> optimizeForSegment(PerSegmentQueryOptimizationContext optimizationContext)

withOverriddenContext

public TimeseriesQuery withOverriddenContext(Map<String,Object> contextOverrides)

withDimFilter

public TimeseriesQuery withDimFilter(DimFilter dimFilter)

withPostAggregatorSpecs

public TimeseriesQuery withPostAggregatorSpecs(List<PostAggregator> postAggregatorSpecs)

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class BaseQuery<Result<TimeseriesResultValue>>

hashCode

public int hashCode()

Overrides:

hashCode in class BaseQuery<Result<TimeseriesResultValue>>
