Interface FilterBundle.MatcherBundle

All Known Implementing Classes:

FilterBundle.SimpleMatcherBundle

Enclosing class:

FilterBundle

public static interface FilterBundle.MatcherBundle

Builder of ValueMatcher and VectorValueMatcher. The valueMatcher(ColumnSelectorFactory, Offset, boolean) function also passes in the base offset and whether the offset is 'descending' or not, to allow filters more flexibility in value matcher creation. OrFilter uses these extra parameters to allow partial use of indexes to create a synthetic value matcher that checks if the row is set in the bitmap, instead of purely using value matchers, with OrFilter.convertIndexToValueMatcher(org.apache.druid.segment.data.ReadableOffset, org.apache.druid.collections.bitmap.ImmutableBitmap, boolean).
