isNullInputUnknown

public boolean isNullInputUnknown()

Description copied from interface: DruidPredicateFactory

Indicator for if null inputs should be considered 'unknown' matches when used for filter matching with ValueMatcher.matches(boolean), VectorValueMatcher.match(ReadableVectorMatch, boolean), or BitmapColumnIndex.computeBitmapResult(BitmapResultFactory, boolean). If returns true, unknown (null) inputs can automatically be considered matches if includeUnknown is set to true on these methods, else null inputs should be evaluated against the predicate as any other value to determine a match
