IncrementallyUpdatedFilterPredicateEvaluator (Apache Parquet Column 1.13.1 API)

java.lang.Object
- org.apache.parquet.filter2.recordlevel.IncrementallyUpdatedFilterPredicateEvaluator

All Implemented Interfaces:

IncrementallyUpdatedFilterPredicate.Visitor
```
public class IncrementallyUpdatedFilterPredicateEvaluator
extends Object
implements IncrementallyUpdatedFilterPredicate.Visitor
```
Determines whether an IncrementallyUpdatedFilterPredicate is satisfied or not. This implementation makes the assumption that all IncrementallyUpdatedFilterPredicate.ValueInspectors in an unknown state represent columns with a null value, and updates them accordingly. TODO: We could also build an evaluator that detects if enough values are known to determine the outcome TODO: of the predicate and quit the record assembly early. (https://issues.apache.org/jira/browse/PARQUET-37)
