Method Details

getFilters

LinkedHashSet<Filter> getFilters()

Returns the child filters for this filter. This is a LinkedHashSet because we don't want duplicates, but the order is also important in some cases (such as when filters are provided in an order that encourages short-circuiting.)

getRequiredColumns

default Set<String> getRequiredColumns()

Description copied from interface: Filter

Set of columns used by a filter.

Specified by:

getRequiredColumns in interface Filter

getBitmapColumnIndex

@Nullable
BitmapColumnIndex getBitmapColumnIndex(BitmapFactory bitmapFactory,
 List<FilterBundle.Builder> childBuilders)

Specialized alternative to Filter.getBitmapColumnIndex(ColumnIndexSelector) to allow reuse any precomputed BitmapColumnIndex created as part of a FilterBundle.Builder
