Methods in org.apache.druid.segment with parameters of type ColumnSelectorStrategyFactory

Modifier and Type	Method	Description
static <Strategy extends ColumnSelectorStrategy> ColumnSelectorPlus<Strategy>	DimensionHandlerUtils.createColumnSelectorPlus(ColumnSelectorStrategyFactory<Strategy> strategyFactory, DimensionSpec dimensionSpec, ColumnSelectorFactory cursor)	Convenience function equivalent to calling DimensionHandlerUtils.createColumnSelectorPluses(ColumnSelectorStrategyFactory, List, ColumnSelectorFactory) with a singleton list of dimensionSpecs and then retrieving the only element in the returned array.
static <Strategy extends ColumnSelectorStrategy> ColumnSelectorPlus<Strategy>[]	DimensionHandlerUtils.createColumnSelectorPluses(ColumnSelectorStrategyFactory<Strategy> strategyFactory, List<DimensionSpec> dimensionSpecs, ColumnSelectorFactory columnSelectorFactory)	Creates an array of ColumnSelectorPlus objects, selectors that handle type-specific operations within query processing engines, using a strategy factory provided by the query engine.
