computeBitmapResult
public <T> T computeBitmapResult(BitmapResultFactory<T> bitmapResultFactory, boolean includeUnknown)
Description copied from interface:BitmapColumnIndexCompute a bitmap result wrapped with theBitmapResultFactoryrepresenting the rows matched by this index. If building a cursor, useBitmapColumnIndex.computeBitmapResult(BitmapResultFactory, int, int, boolean)instead.- Parameters:
bitmapResultFactory- helper to format theImmutableBitmapin a form ready for consumption by callersincludeUnknown- mapping for Druid native two state logic system into SQL three-state logic system. If set to true, bitmaps returned by this method should include true bits for any rows where the matching result is 'unknown', such as from the input being null valued. SeeNullHandling.useThreeValueLogic().- Returns:
- bitmap result representing rows matched by this index
