Gian Merlino 2970b49adc BoundFilter optimizations, and related interface changes. ... BoundFilter: - For lexicographic bounds, use bitmapIndex.getIndex to find the start and end points, then union all bitmaps between those points. - For alphanumeric bounds, iterate through dimValues, and union all bitmaps for values matching the predicate. - Change behavior for nulls: it used to be that the BoundFilter would never match nulls, now it matches nulls if "" is allowed by the lower limit and not excluded by the upper limit. Interface changes: - BitmapIndex: add `int getIndex(value)` to make it possible to get the index for a value without retrieving the bitmap. - BitmapIndex: remove `ImmutableBitmap getBitmap(value)`, change callers to `getBitmap(getIndex(value))`. - BitmapIndexSelector: allow retrieving the underlying BitmapIndex through getBitmapIndex. - Clarified contract of indexOf in Indexed, GenericIndexed. Also added tests for SelectorFilter, NotFilter, and BoundFilter.		2016-03-25 14:11:48 -07:00
